I was playing a war for some time and lately started leveling palading for fun and possible 2.2 class mount.
I was comfortable with tankers need to know every dungeon - i know them all very well.
I was comfortable with tanker being a leader and making pulls - not new to me, i ever failed pulls only when started playing.
I was ok with the fact until lv30/40 it's not very easy to hold aggro on mobs - i know enough tricks to hold it.
But lately i got the worst experience ever since i started playing ffxiv (worse than story dungeons with skip-scene bullying). They give exclusive mounts for high level tankers - ok, since update i will level up my remaining 12 levels using levequests, but not a single more duty finder.
What i got in one evening, in a row.
High level roulette, wp run - see screen: http://i.imgur.com/1GwZ69j.jpg
Brayflox - two mages who kept using aoe (whm asked them 3 times not to wake up mobs) and then dying because i cannot overflash their aoe, at least they didn't speak, but i decided not to go into brayflox again.
Qarn Temple (didn't make sc), owned by Bees, then bard started mocking me and i just left.

Qarn temple, team started normally, but bard grew very impatient and started making pulls before me and then circling around so i cannot do RoH. He told me to use flash - ok i use all mana on flashes, but it cannot hold anything (i36 set), so i just gave up and started attacking 1 mob - bard said i should change my job and the rest started mocking and laughing at me.
Queuing into low lever roulette to get this attitude? Never again, i have two healers and can wait 5 min or so it takes for healer duty finder.
My suggestion to new tankers and those who want to lvl up a paladin (since war has overpower and defiance at lv30): use levequests, they give enough exp to level up your job, and you will not be herrassed in almost every lv20+ dungeon at all! Once you are lv50 - use the Party Finder, since all 50+ content (except daily roulette that can be healed/dpsed) is very faily through the Duty Finder.
