The gear! That makes sense. To be honest, it's the one aspect I haven't looked into in any depth (I just grind it out and don't really note what it does). Cheers for the Poe tip. I've been looking to sub out my ageing Chewy for my Light team as he's starting to let the side down and I'm getting diminishing returns the more I upgrade him. I'd hoped IG-100 would be enough of a blaster magnet to mean I could still keep a healer in the arena squad (Daka is nearly ready replace Lumi) but if Poe's going to get me those shots it looks like he gets the job... at least until I've got a 7 star Grievous in 2028.
Edit: That last reply must have come in while I was typing my own. All good stuff, thanks. I'll go check that thread out.
