Nope, not a QQ about wanting to do things the hard way - that's easy - don't use the stuff (your loss though - my Tauren shadow priest has everything AND the fishing ring with the bonuses of a level 25 guild to boot - it gets XP just from looking at mobs).
Nah, the real issue from my perspective is instances - lowbie instances are being run like you've got a 85 leading the charge - pulls consist of every visible mob, mana regains are near impossible and the corresponding wipes which occur due to overpulls chew up any time savings earned by the fast pace (meaning I usually break even from a time perspective).
On my SP, that's not too much of a problem - I say f-it and just sit down to drink every few pulls so while I'm not topping the DPS meter, no big deal as long as the tank doesn't nerd rage out of the group because the healer is OOM and the tank decided to pull the entire room/boss and died.
What worries me is my healadin - it's my first time as a healer and I'd really like to learn my job now rather then wiping groups at 80+ when repair bills mean something - I'm sure I'm not the only one.
There's also the issue of all of the bad habits people are learning - imagine the joy of getting into an 80+ group only to find that the tank's idea of a good pull is half the instance and neither said tank nor the healer have the item levels to survive the experience.
Finally, more of a side note since the folks on these forums mostly don't seem to care, under the law of unintended consequences, Blizz has effectively rendered moot its twink fix for the BGs as full heirloom gear gear hunters and melee obliterate anything they happen to tab target in 1-3 hits - nothing like having a toon quite literally disintegrate as two or three (or God forbid, five as I encountered in a recent BG) hunters all hit you at once from way out of all spell range - so much for encouraging peeps to hit the BGs.
All said though, my main beef is the instances as >40 the heirloom gear only makes BG opponents tough instead of invincible.
My SP is now 71 and while these mass pulls (yup, they're still doing them even at that level - heirloom gear is definitely over powered) are great for XP I foresee a large number of window licker grade tanks and healers soon entering the Cata instance grind.
