I wouldnt call that "cheese" in a bad way. Its just using available game mechanis by the players to their advantage. Iam tho still prefering using the oldest one with hiding in the corner "hole". Shooting him 7 times with my Ghorn will start his cycle of movement and he switches sides. Then I kill the spawning adds and swiftly shoot him in his face with my IB. After that he is on 50% HP and he starts to move to my corner cheese spot where I carefully again shoot him a few times. Then he starts moving towards me and all that is left if to secure the kill with shooting his face from 5 meters immune to his foot smash close combat damage. The only pain in this figth are the shielded Ultra Psions.
