Best resistance team for TB?

That's the best team in my opinion ;)

I would say leave Rey and R2 out. and put in Pilot and BB-8. The more characters that can expose the better. Zeta on Finn is a must though.

You need the trinity of Finn (zeta), Poe and Trooper.

Then it's any 2 from Resistance Pilot, Rey, R2 and BB8. I have used all possible combinations, and they all work just fine. My personal preference for HAAT/GW is for Pilot (extra source of expose) and R2 (I like the stun and potency increase). However, typically in TB I use zFinn, Poe, RT, RP and Rey, because that frees up R2 to be used in rebel teams, and there's plenty of phases where you need 2 rebel teams.

Hope that helps!

Definitely helps guys, thanks!

Moved to strategy section

I use Finn, poe, pilot, trooper and r2...r2's stun really helps w the countering troopers and I use his burn when there are multiple exposed opponents.

Finn, Poe, RT, BB8, R2. R2 can be replaced by RP if you need him elsewhere.

Zfinn, poe and RT are a must... in tb then I add RP and BB8 but not because they do more exposes, but because they can be used only in a resistance team. So I can use rey and r2 in other teams. Rey is still a strong attacker and r2 is very good in so much LS teams
The best resistance team in general is zfinn, poe, rt, r2 and bb8

One other point worth mentioning to help with your planning is that for HAAT P4 you need one of the droids (R2 or BB8) to avoid the airstrike. You don't need to use one if you use the team in P2 though. I know your post is about TB but it's a team with multiple uses so you might wanna consider this aspect as well.

It really depends on who you have Zeta'd.

The given three are zFinn, Poe (high speed), and RT. BB-8 makes even the hardest of those battles a breeze, and I highly recommend him as your fourth.

I have Rey's zeta, and the extra daze s very useful in later phases when more than one Skull Snowtrooper's tend to pop up. Plus she hits like a meteor once illuminated destiny is active on her.

RP is good for extra Exposes, and hits very hard as well with her secondary, if modded properly.

R2 is good for stealth and stuns, but I prefer to use him with Leia under CLS lead. Plus, the only time you actually need stealth, the spec ops usually just dispel it.
