The spinny thing is a bit unusual its not always major dmg. There is a normal spin attack and like a 30 to 40 sec cooldown depending on traits that make it a special spinny attack. That does good numbers. If you wait till its on cooldown and then activate your crit buff, leap in spin, aoe smash(can fit between cooldown), and spin (This will melt every pack of normal mobs in the open world i have come across), then do the pointy saw attack the burst dmg is insane. But single target get there are some combos that hit really hard too and if you hit ya crit buff and then ultimate. Even though it looks ridiculously silly it will melt most mobs and time X mobs, it will take off a complete lvl.
This is all code for zerker can do some really insane stuff. Plus if ya learn to dash and leap you can be in and out before you are getting hit back in pve and pvx.
I did that 6 man pvp every one against every one instance. I just ran around till i saw people at 1/4 health. Leap in, killed one, got the other guys health to half and leaped out and dash 3 times and go around the circle till I found the next victims.
Zerker is fantastic dps but they go splat (not as bad a slayer but its tricky to get used to at first) Then of course just don't solo stuff
