There's nothing extreme about her on point - it's the great variety of assists she has.
Sing, spear, tremolo, NO NO NO, both her flame breath normals, possibly even Draugen Punch, if that can be used as an assist.
And the fact that they can be charged up by tagging her out after she's got level 2 in either. So NO NO NO attacks seven times on the first time it's used.
And the fact that she can end her combo with the lvl 1 floating orb super and have time to get some charge and tag out.
I think it's terrific that she's super easy to use though. Her combos don't really require much grinding at all, and that's great news for newbies.
