I have 10 85's of all specs and I love to tank but I rarely tank pugs - I'm too much of a perfectionist, too intolerant of stupidity, and don't like helping people who are either lazy, stupid, or intentionally trying to leech.
I get tired of seeing dps that can't pull 10k+ in troll heroics with a 15% pug bonus. Delete your toon - period. Go slap your parents for raising a moron since I can't reach thru the internet and do it for you.
I get tired of seeing people with missing gems, missing enchants, etc and/or pvp gear (in pve content) - if you don't give enough of a crap about your own gear to kit it, why should anyone help you get more gear to blow off? Don't PvPers burst a synapse if people do PvP in PvE gear...well I feel the same way about PvP gear in PvE. Die.
I think most here are fond of saying WoW is zero challenge, ultra easy, easiest game of all time kinds of things...but SO many WoW players find all kinds of ways to fail. No knowledge of content, no clue how to play or spec, don't take care of gear, and so on. For a game that's so easy you'd think even morons could figure out some of it...but no.
For the "tank made me stand in fire" - yeah, that's silly, BUT, a good tank will position mobs so melee dps can dps safely (from behind usually) (and I do this because I know most melee dps are too stupid to move out of avoidable damage). I see pug tanks (or guildies aspiring to tank) who either don't care or don't position mobs well, put melees at risk, waste healer mana, and to summarize - play stupid.
I'm not a big fan of stupid.
And yes, get a guild, get some friends - you might find the occasional good pug but your chances of finding dookie are far higher. Grouping with known quantities, even when they're sometimes idiots, is a less annoying approach.
PS - I really wish bliz would change how they calculate avg itm lvl. PvP gear shouldn't count as high as it does, unenchanted/ungemmed items shouldn't count at full value, it should only count gear for the spec you queue as (playerscore can differentiate by spec so why can't bliz?), and it should definitely not count gear you have in your freaking bags, like unbound boe epics - duh. I'm pretty sure bliz balances content under the assumption that people will gem, enchant, inscript, etc...but then they don't account for it in their itm lvl calc. Why can't bliz make a single unexploitable game mechanic even when it can so obviously be done?

Think of how stupid the average person is, and realize half of them are stupider than that
