Train - corrode (train tracks plus prx win at same time)
Inferno - icebox (lol)
Dust 2 - ascent (the classic)
Nuke - Abyss, all the weird elevations and shit
this isnt true though, at faceit 2.3k elo im playing pretty much all maps regularly except inferno maybe. premier 25k elo even though i dont play that much even there its pretty much all maps regularly too
i peaked like 18k and the only two maps i remember playing that werent those two were ancient and nuke which got so boring i just started only queueing nuke in competitive
