Choke points are points on the map where AoE could be applied very generously to prevent a rotation. Khylo on the stairs is a perfect example of this. What I have seen is mass AoE spam on points, but very rarely in a choke point. This could be because everyone prefers to play burst builds. Necro staff build is very good at this, and to have people do finishers through them could influence whether or not you win the game. Just an fyi to improve your play style and to create some build diversity. The maps you could say are very wide open, but there is always room to choke point the opponent for example on every map. Legacy on the stairs, towards the side where people rotate,Silent storm, on mid, on stair wells, pretty much every narrow bit. Sorry I had no more time to post.
