Maps are completely useless for drops. Only useful currency/items I got last league was from Expedition and Blight. In the past it was Heist but I cba to play Heist again.
And now with alternate quality gems removed from Heist I never ever need to touch that boring shit.
It boggles my mind to this day that they're unwilling to slow the gameplay down by making enemy attacks easier to see coming and dodge, lower movement speeds or the like, but in nearly every league there's some sort of mechanic that forces you to stand around doing absolutely nothing for like 30 seconds on each map, which is even more jarring with the zoom zoom gameplay, not to mention utterly fucks with all sorts of things that depend on momentum, like flasks, berserking, rampage, charges, temporary summons, and so forth. Not feeling like I can play those kinds of builds comfortably and do league mechanics is a big part of why I stopped playing, I think, because I love that shit. Good luck playing your rampage berserking flicker strike character when you lose all your stacks of everything 4-8 times in each map.
