I was 2 away from completing Galactic War. I had the match all wrapped up and set it to auto basic to finish off single opponent remaining and let it run. I was expecting it to be over shortly, but I knew Kylo Ren (Unmasked) would take awhile (as he usually does in later GW matches).
I check it after 5 minutes. Still not dead - full health, actually - from a barrage of basic attacks. Maybe full auto? Ah, but I watched my phone's battery drain for FORTY MINUTES before I gave up.
This wasn't because of lack of skill; it was a simple lack of damage for my level. A level 78 KRU (leader slot) with 2/3 full gold mods, level 7 abilities, and (judging by the purple ring) geared to level 9, it simply wasn't possible for my full Phoenix Squad to kill him.
Only 2 of my characters (Ezra and Hera) could deal more damage than he healed on a basic. I even tried focus-firing him with all high damage attacks manually and keeping his teammates around for the trash firing. As I get him down to a level where I think it's going to work, he heals himself to full by his special attack.
Don't get me wrong; I don't expect it to be easy; I expect it to be POSSIBLE.
TL;DR: KRU single-handedly tanked my full Phoenix Squad for approximately an hour in total. Impossible match-ups aren't fair. Please fix this. :<
