I am fine with most of the maps. I just can't play gimmicky garbage like Hill Fort or Water Maps and I have only one ban.If you dislike so many of the maps why not just play lobby?
In my last 8 RM-TG's as a soloQ-er I had 6 different maps and I enjoy it.
This is what I always expected MM to be, different maps, no dodgers (not a single dodge/ALT-F4, only 1 game with 3 drops after a pause) it's great.
Of course the mappool itself is not the greatest one we ever had (by far not) but you will never make evryone happy in that regard.
