As someone who plays TT, i'd rather keep her nerfed.
the mere chance of her returning to be popular in TT is a dreadfull though...longranged waveclear+harras, high lvl 6 burst and a hard to avoid longranged aoe stun are pretty masiive in a map that is about svae pre 6 laneing, level6 playmakeing and 3v3 fights.
The map is so small that you have little room to avoid 2+ guys getting stunnned by her E, and the brutal singletarget burst of her ult is pretty nasty, as bursting down 1 guy already removes 33% from the enemie team, rather than 20% like on other maps.
though i do agree, they should revisit their nerfs, and even more so look at some more champions on those maps, right now it's pretty half assed work, they nerfed a couple of chaps a long time ago(those nerfs were justifyed back then), but never took a look on them again or nerfed other champs...
