I have maxed SG, and test her in a match. I can confirmed that her green ability generates AP by destroying tiles. And at level 5, there are 4 green CD on the board once you collect enough green AP to fire the ability.
Anyone noticing she's not close to unbeatable
...they would give her "more HP"... but she's just another old 6.8k HP character!
I also thought it was funny how someone blamed SG for getting killed by Ares, and not their own gameplay or the power of Ares.
