Bottom line is, CG reworked Fives and as such, his abilities work differently to the point where it is a significant change. They should've just made his taunting ability level 1 again and said, "it's all refunded, do it again if you want!" and been done with it.
The fact they do it sometimes and not others when they change a character is at the least, problematic.
I didn't omega the ability at first because I didn't have the resources to build him to spare. After his rework I didn't add it because of his zeta ability. Why would I want him to taunt and die? I want another clone to die...
