the Kat just does not deal out damage fast enough. ago It doesn't matter if the RPG detonates, the blunt headshot damage still applies.
with a Kat you would be swarmed while swat-flinching a Scrake and pummeled by a FP before you could kill it. The funniest thing I've seen is when someone tries this but they at just the right amount of distance (despite closing in on Scrake) that the rpg still detonated and he dies along with the scrake Mushnag 10 mo.
On the crane wave a level 6 zerk on HOE solo can stand still for 2 mins. I even made one of my own KFO map to have a wave like that. no FPs or Scrakes so the Kat is perfect for use there. like the container wave in KFO Frightyard. If I am being serious as a zerk I use the alt-fire on the Claymore, I fnd the Kat can be fun but pointless beyond that, I normally just go from axe to claymore and not waste my money on the Kat upgrade. so a commando opening up on a scrake will have no effect beyond dealing damage. When you have a scrake stunned he won't un-stun from fire unless he is hit with something that should stun him and misses. You can not un-stun a scrake being flinch-locked since he is not stunned to begin with. for Zerk there is the 'flinch-lock' and 'stun'.
