Wicked Solo clarification

I was just running a playtest with several of the Daybreak characters, and a question came up:

When Rockstar's "Wicked Solo" ability says that the target must take the Attack action against her, does that mean... 

a) must take the basic Attack action against Rockstar, i.e. no using Abilities, or

b) must have an Attack on her as part of the next thing they do - so an Ability that includes making an attack on her is acceptable?

It seems like having the ability to automatically force an opponent to target her is already pretty good for a Green ability, but that ability gets a lot better if it also means that she's shutting down an opponent's Ability use for as long as she keeps hitting them with Wicked Solo.  Which one is the intention of the rules?

Any attack works whether the target is doing that as an ability or basic attack.  

After further playtesting, I have several more questions.  Neither is really about Wicked Solo specifically, but both derive from a situation that came about as a result of Wicked Solo being used.  

The situation was - Daybreak is fighting Myriad, and Rockstar is going toe to toe with him, using Wicked Solo every time to force him to attack her on his next turn.  This is sucking for him, because Myriad doesn't actually have any abilities that let him attack and do something else, so he can't use any of his awesome swarm-generating abilities.  Daybreak pretty quickly had him locked down - Rockstar was hitting him every turn and forcing him to attack her, and even though she wasn't doing any damage and was generating a minion with every attack because of Made of Bugs, the others were able to keep pounding away at him - Aeon Girl mopped up all the pre-existing minions pretty quickly, and without the ability to create more, Myriad was just continuing to eat attacks from Muse and Aeon Girl that he couldn't stop with Made of Bugs, slowly whittling him away.

There's obviously more to this specific situation - the scene tracker and environment effects meant that the combat wasn't going to just boil down to that - but it still raised a few questions for me:

• Made of Bugs, like several other abilities, refers to "physical" damage.  Is there a hard and fast definition of what this means?  Unlike in the card game, each attack in the RPG doesn't have a clear keyword for what damage type it is.  Is this just left to common sense?  It seems pretty obvious to me that, for example, Muse's psychic attacks using Mental Block weren't "physical" damage and wouldn't trigger Made of Bugs.  But what about trickier cases.  Would a blast of fire be "physical" damage?  A blast of supercooled air?  What about a shower of ice spikes?  Is it just GM's judgment, or is there a rule?
   
• Myriad's lack of any abilities that incorporate an Attack action made me really want to let him use a Risky Action and take a minor twist in order to do something else while also technically "attacking" Rockstar by doing damage with the Min Die or something.  Can villains take Risky Actions?  It sort of seems reasonable to me to let them in situations like this one where their specific ability spread is straitjacketing them in important ways, but it also struck me as possibly breaking the game (for instance - if Myriad takes physical damage from a minor twist, can he then ignore that damage and spawn a minion with Made of Bugs?  That seems pretty obviously abusive).  Is the flexibility provided by risky actions supposed to be something that's only available to heroes as part of their "PC Aura," or should significant villains be able to do it too?  For that matter, are there any other situations where villains can accept twists in order to invoke special effects in the same way that PCs can?  Can villains even take twists, or are they something that only happens to heroes?
   
• The other obvious solution to Myriad's dilemma with Rockstar was to have him just fly away from her - he's got Flight, and she doesn't, so he should be able to just lift off and go somewhere that she can't easily follow, up on a building or something, where he can make his minions in peace without being constantly pounded by Wicked Solo.  But can he move like that?  He has to Attack Rockstar, but can he attack and move somewhere?  Normally, characters are just assumed to be moving as makes sense in the scene, but what about situations like this, where the movement is tactically important?  My instinct would be that, to move in a way that has serious ramifications for the scene, you'd have to do an Overcome action - which would mean Myriad can't do it, because he has to use his action to attack instead - but on the other hand, he can fly, and all he has to do is go up - should it really be something he has to roll for?

Also, on Wicked Solo more generally (or, I guess, Frontline Fighting, in the main rules), I'm leaning towards the conclusion that it probably needs to be tweaked a little.  If it's generating rules conundrums every time I try a test game that has Rockstar in it, that's probably a sign that its design needs to be re-examined.  I'm thinking that it would make more sense if it inflicted a massive Hinder on the opponent's next action if that action is anything other than attacking Rockstar .  So she's still acting as the "tank" and putting pressure on the opponent to go toe-to-toe with her instead of the team's squishier members, but she doesn't have this absolute power to force any opponent, no matter what, to attack her over any other concern - that doesn't make a ton of sense unless what she's doing is actually mind control or something.

For number 1.  There isn't any hard rule I can find.    At least in my view any attacks using powers under elemental/energy and pyschic are not physical attacks.  Any other power used in attack would be considered a physical attack.  

Can villains take Risky Actions?

But can he move like that?  He has to Attack Rockstar, but can he attack and move somewhere?  Normally, characters are just assumed to be moving as makes sense in the scene, but what about situations like this, where the movement is tactically important?  My instinct would be that, to move in a way that has serious ramifications for the scene, you'd have to do an Overcome action - which would mean Myriad can't do it, because he has to use his action to attack instead - but on the other hand, he can fly, and all he has to do is go up - should it really be something he has to roll for?

As to Wicked Solo being the sole focus of attacks by the main villain doesn't always end up well and with Myriad it means hitting him with that generates more bugs to attack Rockstar.  I would be surprised as well if there isn't counters towards it we have villain creation rules.

Thanks, this is really helpful!
