Arvel seems like a tier 1 blocker to me, with double re-positioning and the possibility of shooting at range 0. The idea of combining him with Sense or Cassian was discussed a little in this thread, pairing him with Lando and Luke. I tried that a couple of times but have more recently been running him with Wedge, Ezra and Biggs. The idea is to sense with Ezra, block with Arvel and cripple with Wedge. Biggs is in there to keep things alive.

I'd be interested if anyone's flying something similar or if anyone's got any suggestions for improvements. R2 for Biggs seems like the right call. I've found that it's been useful on Wedge as well although it's not always easy to dis-engage.
I'd love to double mod Wedge's shots, but hey, you can't have everything!
