Not a bad idea, but I would like to see her have one of these 2 abilities as well.
A sun sphere shield aura, which makes her invulnerable for a few seconds, so that she can either survive a gun fight with a Scientist better when forced to do so or just be able to revive someone with out being worried about getting killed. You see a fellow plant fall *shields up* time to revive them.
Also the big one I would like to see is a mobile offensive attack high burst dps ability. Again if she she faced with a threat like a Scientist or an incoming All-Star she has one way of actually having a chance of surviving or getting the kill if you want to play as a glass Cannon.
