I never had too much trouble, though I'm hearing recent changes have made it harder for low level tanks to maintain hate, but I haven't tested that, nor do I think a test with sync'd down gear is representative of tanks at that actual level.

I only ever had the same few problems as tank that recur in early-mid pug queues.

1. Some people don't announce what they want in a pug queue (fast runs or full exp runs), or announce AFTER they're already p***ed off. Might result in non-tanks forcing pulls onto me, or people leaving without saying a word. In the case of wanting fast runs and choosing anger, the complaint often comes from people that don't realise that Leveling Roulette primarily exists to pad out the numbers for people who queued for one specific dungeon they need. It can happen, but you should not go into that queue if you're not going to have any tolerance for the people that actually NEED to be there, whether it's for the story, company hunting log, the side loot or whatever else. They are the main reason the queue or the scaled completion bonus exist.

2. Dungeons that exist outside of the main story have a lot more confused people running around. The Sunken Temple of Qarn is probably the best example. I've seen two wipes on just the first first boss before even one DPS decided to read chat and help with wespers or stop dying to doom. I've seen the statue heads die as much as 5 times before a DPS realised that the rest of the party was trying to put it somewhere specific. I've seen a DPS enrage toward the tank for not getting pulling the boss all around the arena to pick up the squishy statue adds. I've seen someone who wanted me dead IRL for mentioning the former and latter. (I mean I lost my patience too but it does get a little unfathomable when people seem to play with their chat log hidden)

3. Ties into 2, but people don't look at mechanics preceding a dungeon. It seems like it's fairly common not to, but it's very poor form in front of strangers, and poorer still if you wait as late as the bosses gate to tell everyone to stop and get filled in on what to do. It's actually quicker for yourself if you go and do your own independant research and find the bullet points or video, rather than waiting for a type up from a party member. Not to mention the DPS of all people could have done the little checking they needed many times over for the duration they waited in queue.
