I can get over most of the stuff many of the other players are complaining about. The one thing that really ticks me off is the volcano mechanic. It doesn't matter where I am in the world. If i'm on a screen for more than say 45 seconds, I start getting carpet-bombed by the burning rocks that ensue. I do mean carpet bombing as well. It's not like there's a few rocks so you can dodge your way out of it, I mean it's like the shotgun blast but with the speed of the machine gun, but from the sky across the whole map. Super hard to get anywhere in this game with the frequency of the debris.
