im getting sick of seeing people say alcoves are pointless

like you guys can't be so dumb that you don't see the strength the alcoves bring in ganking potential...

example, the lane's pushed into one side's tower, and about to reset. well, now the jungle can run into the first bush leading to the alcove, slip into it and hide behind the wall(which keeps him out of sight), and then wait for some poor support to step into either mid bush or for enemy laners to push past it. then the jungler comes out to gank, catching bot laners by complete surprise and turning a 2v2 into a 2v3.
