Possible Squad Arena Team

Viable.

You need to look at your shard and see who is top 50. At 85, top 100 are all CLS. There is a lone Thrawn, Krennic, Veers, DT, IST team that challenges the CLS dominators, but nothing else. 50-100 is Wiggs/Chaze/Leia or Boba and Sith. Beyond 100 is a mixed bag, but mainly Wiggs/Chaze/insert toon.

So join the cookie cutter crowd. Make sure you speed the tarp out then all and secondary speed as well.

Scarif Pathfinder, no. That's a character who looks good at first glance and he does okay on missions & events, but he doesn't enhance/supplement the team nearly enough to earn a place on an arena team.

Besides, Scarif's one & only good trick (repeated resurrection) can be countered by any character that kills him with a dispelling attack, or any character that inflicts buff immunity. And there are many who can do that.

Without going into a lot more detail about the mechanical differences between Scarif & other tanks, and why other options are better, let it suffice to say that he's been tested already by countless player and they rarely/never got better results with him than they would have gotten with the more popular Rebel tanks.

If you want to use Biggs & Wedge on an arena ladder that isn't already overrun by Darth Maul or Commander Luke & R2-D2, either look toward Stormtrooper Han (quick farm, mod him with highest speed stats possible) or Baze & Chirrut (very slow farm, they only operate well in tandem, mod Baze with health/prot and Chirrut with crit damage/speed).

Eventually you'll need to move on to a bigger & badder combo as these will inevitably be rendered obsolete in arena, just like Phoenix. But they can be viable for a while anyway.

Moved to strategy section

What about Wiggs, Barriss, ST Han and Ezra (since i already have him g9) with wedge at lead?

wiggs sthan ezra and boba is good for early-on shard

Barriss will do since she cleanses one each on her turn, but you can find better options as your roster develops

Keep in mind: whatever your arena team is: try include these.
1. Dispeller (the one that remove enemy's buff) Nihilus does it on Basic, Baze does it, Boba does it, CLS, Thrawn does it, Deathtrooper does it. You need a dispeller to remove taunt.
2. Tank. tank has to soak up the damage. he needs to taunt. If he can't, at least get a character that does similar thing to taunt. Such as R2. He uses smoke screen and hides everybody but a tanky character, making a pseudo-taunt. Tanks that taunt at the beginning of encounter are superb. Old Ben zeta is awesome, because he taunts again after taunt being removed. So the enemy has to dispel twice. This zeta works against even thrawn's fracture.
3. Cleanser. (One that remove ally's debuffs)
When your shard is full of characters that apply powerful debuffs, you need cleanser.
Rex, Chirrut, Ackbar, Thrawn, Fulcrum (On herself), Commander Luke (On himself), R2D2 (When he gets combat analysis zeta), General Kenobi, Barriss are eligible.

These three features are imo almost indispensable for any arena team.
Below are some more features that helps.

1. Stun. Kylo, CLS, Han Solo, Thrawn (Practically a supreme stun), R2D2, Daka, Kylo Unmasked and many others
2. Ability Block. Boba, Thrawn, New Rey, Old Ben and etc.
3. Revive. Not very good. Zombie is good tho.
4. Heal. Also not necessary but helps. Barriss Zeta is the best healer

Try to maintain these three in your arena team, always.
1. Dispeller (dispel enemy buffs) 2. Cleanser (cleanse ally debuffs) 3. Tank (taunt, or make others stealth except one tank)


With that perspective in mind, your team seems alright.
Ezra dispels, Barriss cleanses, StHan tanks.
However those three barely do their roles.
So in time you should replace them with better ones.
One suggestion is chirrut and baze. they do all 3 jobs. Tanking, Dispelling, and Cleansing. You could add R2 to assist Baze's tanking with smokescreen and number crunch zeta.

Some other eligible toons are Thrawn, Rex, Nihilus, CLS, Old Ben, General Kenobi, Jedi Rey&BB8&R2, etc. Obviously all OP but they do one or more roles really well.

Also in time you want to replace wiggs. They are squishy and as your shard develops, will become the weak link of your team.

Boba is also a cheap and very useful toon

As for zeta, reconsider giving Barriss your first ever zeta set. Surely her zeta is one of the greatest, but without a well developed General Kenobi, it is very easy to deal with her. Also, the new Rey team beats zarriss team so easily, that zarriss is quickly being vanished from the old shards.
Consider R2's Number crunch, CLS's It binds all things, Han's Shoots first, R2's Combat Analysis as more prioritized abilities to invest in.

I agree with you on everything, the problem is that I'm looking for a something i can actually work on. I’ve considered farming chirrut since he’s in fleet, but baze is completely out of reach. I’m only level 72 so getting him even from hard battles is a long way off. I’ve been told chirrut isn’t worth having without baze. Is that true? I also agree r2 has great zetas. I just missed him this time around which sucks. Just not enough time to get a full 5* empire team around and keep up in squad. Obviously without r2 i won’t get cls either at least not for a while and i’m still quite far away from having the characters for him. Again i’ve only been playing for 2 months almost exactly now and I’m looking for a squad i can actually farm that will be viable for a few months till these legendary characters come back and I can add them to my collection. I’ve been considering getting jyn and cassian and possibly k2so (easy gw farm at 15 shards a day). Are those characters worth working on?
