Performing poorly numbers wise because your gear is shit is understandable. I never call names on recount for that. I remember how INCREDIBLY SHITTY my DPS were at fresh dinged 90 lvl hunter which had 9% Crit, opposed to 40% unbuffed in DS HC gear @ 85.
I don't stand however lack of competence, not following simple instuctions or plain botting / afking.
Freshly dinged 90 doing 20k dps is one thing. But afk bot doing 3k because it cannot push the damn button on Taran Zhu (so 90% of his attacks miss), bleh ban them all.
The math disparity between fresh dinged 90 and heroic raider wanting VP will grow overtime into the expansion, because we are experiencing really steep ilvl inflation. The jumps of ilvl between tiers and gimmicks (heroic elite, thunderforged, heroic thunderforged, yadayada) are immense and if it goes at this rate I pictrue myself easily pulling 200k+ sustained DPS at the end of siege of orgrimmar heroic. I pull 100k-ish now, and i have only 503 item level without a single HOF/TES heroic item equipped. My gear is only upgraded 496s and MV heroic items. It increased by almost 100% from "baseline" 463 full blue equipment - pulling 60k on normal Feng first reset was acceptable, 70k was godly, achievable with expensive BOEs and 80k-costing DMF trinket.
It will propably end up like late dragon soul - me queueing into end time, with 4 people around 370-ilvl (myself 407 BIS) i'm doing 70% of the damage. Could duo this with healer. And it was okay, people wanting only currency speed it up for fresh players, I'm not mad at doing 70% of dmg solo as long as the rest of that party cares to try.
