The Dreadnought map. Mob respawn, no checkpoints.

To be honest I've no idea who thought it will be good idea, but running over and over the same map in campaign because you died, because mobs COULD jump behind you and block/sandwich you is absolutely terrible things (Imo actually mob respawn is a worst part of the game).
On The Dreadnought map there is literally NO checkpoint throught the whole map

How is it possible that someone thought this would be something players would like?
