Putting a zeta on your stormtrooper forces your opponent to take him out first. At the highest levels, he becomes nasty when you lose two or three toons and he can sometimes save a loss.
Yeah, I understand you may not believe me but I’ve faced a high level/gear/mod stormtrooper with a zeta and I avoided him until last and ended up losing.
Either way I don’t care if you don’t believe me but, in the future, try to avoid bashing an opinion without having one of your own.
No one believed me when I said Rey was good neither and it didn’t stop reality.
In conclusion, do what you want, it’s your game.
