Well, Chimera lightning seems to be better now, but Norfenstein and I have found something kind of weird with it.
A) Lightning seems to deal damage through (thin-ish) walls, and when it does so it deals more damage.
B) Lightning seems to do more damage to everything else when it hits a structure. So if a Chimera starts jumping around a group of turrets and one human, it does extra lightning damage against everything, not just the turrets.
C) Personally, I think the Chimera lightning is just a bit too powerful right now. A Chimera can just hop around a base zapping things with impunity right now.. I think after taking a look at A and fixing B the damage should be toned down slightly, more playtesting will be needed to see how much though.
