I consistently finish top five on my server at lvl 60. I run 7* Sid, 7* Lumi, 6* Luke, 5* Poe, and 4* Dooku (all purple gear). Obviously it is a young server. For GW I run the same team except I swap in JC for Poe in the early rounds, then sometimes add Poe for Dooku in the later rounds. For some reason my GW is ridiculously easy (knocks on wood). I rarely need to restart a match and I haven't failed to complete it since my first few attempts back when I unlocked it. Before the changes GW felt like a challenge (maybe because I didn't know about the force close BS at the time) but these days for me it's just another daily activity.
