Shouldn't make too much impact. The burns increase accuracy slightly and only add ~100 to max damage. Even in just the darkmeyer outfit. no pots prayers or other boosters I could easily down them in 2 - 3 hits. Plus good thing is right by bank = bank corpses as you go = easy maxing of the weaponary I highly doubt you're killing them in 2-3 hits consistently, because in bandos + overloads + turmoil, while I did do it sometimes, it more often than not took more than 3-4 hits. What's your kph? And banking slows down the task more than you would think, even though it's close.
