Dear droid users, advice?

i have rg but i never used in arena, my arena rank is 1 - 10 with stromtrooper han as my taunter

It's hard because if i focus on rey first i can't completely kill her, only if i'm lucky but most of the time she is in red and then i still have to fight the full RG so won nothing actually

Exactly. This is the primary reason why you don't win this fight all of the time. There is no other toon that will replace Rey and still give you as much trouble. But... if you can't kill Rey and/or finish her off with AOE after RG taunts with a fair degree of reliability, you should be trying to avoid this fight. (Unless the RG is an undergeared powder puff).

Even worse for Droids is the Ben/Han/Rey meta. Good luck with that one. May the force be with you.

AI mostly attacks the "weakest" toon. "Weakest" meaning the one with the lowest power. To avoid that, you'll have to star and gear up your JE.

lets talk about omegas. Your first omega must go to hk leaders ability, your second omega must go to JE recalibrate. after these two, I would go to ig86 second ability, then ig88 second ability

I hear plasma as a 5th works well too. Use victory march on her first turn and anyone on the opposition slower than her could be hit 2 to 3 times by the same droid before their opening turn.

Hk lead
88
86
Jawa engine
Royal guard

This is the only lineup that will hold your place. You can sub in a maxed Magnaguard if you need to beat another Jawa Engineer team and go first, or your B2 for an offensive role. But always bring your RV back for the final battle.

@RenanFilipe Good call on Omegas. My first actually went to IG100's basic. My second, to his AoE. At the time, I had only just broken past the lvl70 point and 100 was easily my most valuable droid. HK's leader ability came as soon as I could get it but I'd already put 2 Omegas on GG to make him viable and one on 86's assist (+88's basic I think).

On the topic of AI targeting the lowest power toon, although my JE is only 6*, he's more powerful than GG who's still on 5*. JE still gets smacked up early but it's 88 that gets fuct over and out first. I would agree that the AI targets the lowest hit pointed toon and tries to remove them first. Most AI algorithms are written to emulate player behaviour to a degree and I'd say on aggregate, most players will focus down the weakest link early to gain numerical superiority. Player strategy adapts to those small variables in a way AI cannot though, for example targeting RG first or leaving weakened toons so as not to trigger RG's taunt. It's the reason why some teams are so lop-sided in offence vs defence.

4* is fine on offense. Run HK/88/86/SThan/JE. It beats everything handlidly except Rex led teams. Just avoid them entirely.

I hold my place fine. RG is too easy to circumvent but Han getting his TM involved in the game combined with the HK crit TM keeps the team from letting off the gas. Obviously if they have QGJ and save his dispel Hans value is less but even if there are two-three attacks before the dispel it's worth it.
