Mythic R2-D2, Strategy/Issues [MERGE]

I just 1* it with cls lead, raid solo, r2, fulcrum and Ezra. I know you don't have cls but if you have fulcrum she just may help you out. Out of those guys, she was my last one standing and finished off the last 3 or 4 chars by herself. No zeta on her either. It was a pain and probably strictly rng but a win is a win. It felt like I at least had a chance on this one. I didn't even get a shot off for the bb8 mythic. I don't know stat for stat. For each of my chars by memory but they are gear 11 or higher and have my fastest speed mods on them except Ezra. Hope that info helps, good luck and keep trying. I heard for bb8 it took many people with great chars many many tries to get the rng to beat it.
