Tell that to the guy on Vaniki who lost some DPS races to me and spent THREE DAYS flipping out about me in general channels to the point that he got suspended for disturbing the peace, then logged on with a different account and did the same thing with the same results. When I logged back on I had all these people asking me what I did to generate tons of hate in the general channel.
Long story short, I (level 40 SK, which was max level at the time IIRC) was soloing the Frenzy room when this level 40 Cleric popped in out of nowhere and just sat there. Frenzy spawns and I DPS race him on it. Knowing he's got potent undead nukes, I drop Harm Touch and win easily. Guy flips out at me for "appearing in my camp and stealing it" which is the exact same thing he was doing to me. I told him I'd been there for like an hour already and he said that was a total lie, HE'D been there. (I later realized that he was probably in a pick that collapsed and didn't realize it due to being afk or something like that, causing him to appear in the room with me). He stuck around and kept trying to nuke my mobs down, but even without Harm Touch I got the kill on every mob and the next Frenzy as well. I lied and said I had four FBSSes in the loot window (I'd gotten one) and the guy gated out, then spent days ranting about the experience. Edit: I think he tried to train me out before he gated and that obviously backfired. Not even sure he gated, he might have just died out, was 3 years ago.
A good cleric probably could have beaten me on the non-HT DPS races, but not one that was juiced to the gills on SSRIs.
