@mamba previous to the update, when kylo would use his zeta ability, he would gain millions (or if not millions, a whole heck of a lot) of protection points back Above the amount of protection back based on the damage dealt, making it possible to consistently attack/escape, etc, without running the risk of him dying, so long as you did so prior to GG getting enraged.
Now, he gains only an amount of protection back based on the damage he's delt with his zeta ability. Someone please check me on that to make sure I'm not giving out misinformation, but that what I got from reading the update.
However, according to some, you are still able to do so.
Main point: I was simply curious to see if you could still run him solo in p1 or if the fix affected that.
