I noticed this in the current PVP tournament: while I see animations when the friendly Human Torch’s powers trigger, those animations don’t seem to play when the enemy Torch uses its powers.
I do see the little little flame animations when the enemy repeaters tick down, but nothing when the green or red actives are cast, or when the yellow passive triggers.
I guess some things changed in the daily data push, since I am seeing the animation for the enemy’s yellow passive now. I don’t think I’ve seen anything for the green or red powers though.
Edit: it looks like all the animations are working now: I just hadn’t noticed them in the few matches I played.
