I managed to beat insane using 5 revives + premium buff, and still just barely. If the boss wouldn't have so poor cooling i'd have no chance. Got around 10 normal epics, but no legendary. About paints: 9 stripes and 6 stars. I used around 300 fuel on normal afk farm (autoplay can't beat hard by itself). I'm gonna grind a little more while 8h premium lasts. Hope i get more stars.
Oh damn. My mech is even weaker and i barely completed hard mode, but i'm still gonna farm on easy because i'm doing everything i can for a new decent weapon
I farmed at hard as well and only got 1 legy in like 600 fuel, but a lot of epics and paint kits. Also i was able to up some power kits with the rares.
