Magik is too powerful.
So let me get this straight, kabam, you nerfed regen champs in alliance wars and for what reason? They were too powerful? Yet a magik can be put on basically any node and can full wipe your team just from her limbo. That seems a bit ridiculous, don't you think? That's not even including the fact that she can have mystic dispersion to further add to the limbo frequency. And to all those that will say "well you can use your own magik to counteract her limbo" you obviously haven't fought a 5* magik that's immune to debuffs.
