the ONLY thing wrong with Doorman is his fucked ult visual
you'll be standing on top of someones locked body, see the key unlock and prep a 3 just for them to spawn 15 feet to your right and you whiff cart.
THAT needs to be fixed the most.

I use them in the following scenarios
>OH GOD OH FUCK
if you have no doors set up and shit happens, I just chuck them out while rounding a corner and hope the enemy is retarded enough to think you went through it.
>stealing farm
put up a door near your side of the map and place the open door near you, if anyone comes up to try and kill you while you're taking the sinners you just walk through the door and get away/get a free 1v1 after they chase and you close the door.
>walkers
put a closed door behind your walker, wait for them to push then when they round the corner open a door and toss the cart
or just be a lazy fuck. ult them and then cart them through the door.
>LANING, VERY IMPORTANT
place your doors near their stairs and a door about 10 feet above on the wall adjacent to shop, you can harass them out of soul range/get free poke by just chucking shit through your door.
