If the player base had an option of 8 different tanks and only 2 dps...the ratio of dps to tanks would still be the same.

Most people don't like tanking or the responsibility that comes with it.

In DF, I have to almost psych myself up to tank a dungeon.

Things that go through my head are - Will the healer want to heal...or just DPS? Will that lvl 46 archer (not bard b/c he's only deeps yo!) run ahead and pull packs of mobs cause that's his job? Will the Boss do a mechanic that randomly targets a party member (2nd boss WP) and the party freaks out "keep hate tank WTF!!!1!" Will someone say, hey...this tank doesn't even use Rampart...what a noob when I am clearly a Warrior.

Now when I queue for dungeons as a BRD...I can sit back and watch tv and not deal with ... not the stress...but the ignorance of many many players.
