The Doorman is dead, long live The Bellboy. Lend a hand in every teamfight by blowing your enemies up and decimating Walkers. This build is about supporting teamfights with insane AOE damage from the back, as well as instantly clearing waves and doing healthy damage to Walkers. Doorman is very good at soloing Walkers so long as you have an exit door ready to go. Don't be afraid to push up a lane if your team is on the other side of the map and winning their fights.
