So it has happened a few times now: getting kicked in a game of eggwars (op, even though I prefer playing normal), with the reason: 'Breaking blocks too fast'. Every time this occurs, it's when I'm mining obsidian with an efficiency 2 diamond pickaxe (Overpowered items, cost: 5 gold). I don't know why this happens, I find it incredibly annoying, and it'd be nice if something was done. Oh, and it's not because I use some sort of hacked client. Thanks!
