I like to use the sniper over the wall, so DON’T block ANYTHING! If you don’t like doing it (shooting over the wall) then don’t do it, simple, why screw it up for others who like it this way just because you don’t? So as I said the simple answers to all this is play it the way YOU like it and leave the others to theirs… So I vote NO BLOCKING…
but ceiling will be introduces. It was mentioned by Kevin that they disabled ceiling for test purposes. I hope they still haven’t changed their minds and it will return.
