Thoughts on a Zarriss team without GK?

Crazylazyguy

So, I am thinking about a team of
Zarriss(L) - 10% bonus HP for all allies + 4% HP recovery(from Barriss max HP) at the start of their turn
Chaze(I know, I know don't boo me, I am dropping them as soon as I get GK) - Durability and Damage
zR2(NC) - Bonus HP from the 2 rebels(3 with R2) = 30% bonus HP, share 10% of his HP with light side allies.
Nihil - Insta kill(duh)

So in theory this should be a pretty hard to kill team for a Crit based team, right?

Edit - wrong section, sorry about that @Kyno @Vampire_X

Faa

Single 30K crit from CLS and she's dead. You preferably want the defense from GK's lead

Zarris need GK Lead as much health bonus you can get with mods, extra protection and defense are welcome. She is easy killed without his leadership, or without at last 2 good tanks with taunt. GK Lead, Zarris and R2 with double zeta is Hard to kill, i run them with Thraw and Nihilus for Arena
