Nihilus Lead Idea: And no, this is not a nerf nerf nerf thread, but A Legit Thread lol

Ok So, been thinking, and I don't have the zetas for this, one of my shard mates came up with this idea.. How about: Nihilus Zeta Lead, zBarriss, Sith trooper, EP, and Maul/Vader? Nihilus would get rid of all protection and make it health, which makes it so each sith toon has like 60-80k health, which also makes it so, anytime a sith is crit, they gain like 15-20k health from zBarriss! It sounds ridiculous on paper, but no idea how it would actually perform. I cannot imagine facing that, when you crit and they gain like literally 15-20k health. The reason it would be so deadly, is because you have to focus zBarriss, but when you do that, Nihilus has his ultimate ability charging, which means one of your toons is basically sacrificed to Nihilus if you focus on zBarriss. But how can you kill Nihilus, when if you ever land a crit, he gains like 15-30k health?
What's your thoughts?!
