I've been encountering this a lot lately... I que for a random heroic, or in some cases even pug the weekly and the first thing I usually see:
-A mix of DPS and tanking gear, oddly all the tanking pieces have blue gems and third rate enchants on them, while the dps pieces are significantly better and have epic gems in them.
-The Lordaeron shield, and or an ilevel 200 vendor shield, usually using a mace or sword from TOC 5
-Brewfest tanking trinkets, this is usually the mugs but sometimes a mug and the Brawler's Souvenir.
-Cheap +stamina armor patches thrown on random pieces to substitute real enchants.
When they play I usually encounter the following:
Lack of awareness: They will run up and aoe mobs, ignoring the fact that one or two may run off and attack the healer or dps.
Attitude: A lot, im not saying all, but a lot of these DPS tanks have an attitude, any attempt at advice, or criticism may it be constructive or otherwise usually ends in a quick outburst followed by them abruptly leaving the group. This isn't a big deal for me because I have a tank spec, but in the middle of a pull it can be annoying.
Anyway im not really sure what the point of this thread is... just a rant I guess, because I've been encountering this a lot lately.
