Blocking is what gets you banned, not pushing (also by pushing i meant click pushing, which was removed.)
then its a map problem, not really the players' fault. there should be more than one way to the win, and chokepoints should have alternate, more dangerous (maybe faster) routes.
and considering you can push others why can't you just push the blockers out of the way? i get that sometimes they're preventing a necessary jump, so see the above point.
