Anyone have a max R2 yet?

I also saved gear and was able to gear 11 him yesterday. Unfortunately, my team was better without R2, but he's still a good trophy toon to have. I used to run Rex lead, chaze, gk, nihilus. I tried subbing in R2 for both nihilus and Chirrut, and the team wasn't as good during those trials. Today I'll be subbing out gk for R2, and will also try gk lead and sub out Rex. I'm hoping one of these setups is on par, or better, than my old team, but I don't have high hopes.
It looks like he fits very well into resistance and Jedi squads though, so I'll be working towards one of those.
