"This is my playstyle" is a poor argument for being bad.

the loot in the vault is ilvl 142. that means you don't have to be ilvl 142. 136 (from the dungeon before) should be more than enough. was the ironworks ilvl 120 or upgraded to 130? and healers in this game are so overpowered i think 120 is fine for the vault if you know what you are doing.

It'd be tight. Trash and the last boss in the vault toss out quite a bit of damage.
