I am pretty sure that the idea of a chokepoint is that there is only one way to a place
in badwater there are three ways of going to point a - if you're being blocked on the cart path, you go over the hill either left or right
in hoodoo, if you're being blocked you just... watch your teammates run into sentries and snipers over and over whilst the heavy medic charges an uber
one of these is good design, the other is not
