Im not posting my UI or keybindings because i am a competative player and consider my binding setup personal to my playstyle.
I regularly hit 10k+ hits. This was just insane though. It was about 3 weeks ago. Without boring the detail. It was pre-setup and communicated on TS when i was going to hit this guy. So i had most class buffs on damage active.
Also, to further prove that this can't be pre-1.2 as people have suggested... it's frikkin' Novare Coast.
