Don't be "that DPS"

[Malicewolf]

But... If you're doing end game the tanks should have no issue holding hate from you... If they do, they're bad sorry. Unless the dps attacks before the tank does that is, which isn't a dps thing, but a personal thing.

I don't totally agree with this. I do think myself a fairly good tank. With ilvl180 gear, I was able to keep hate from ilvl 205+ players, but they would always be on the cusp of taking back from me, especially if they had their rotations down pat. My flashes weren't enough to spread enough enmity in comparison to how fast they were hitting their combos. Gear differences can make it very hard to hold. If I had messed up my rotation even a bit, I definitely would of lost aggro on a few things. And honestly, may have it weren't for the fact that the high geared DPS were on point in burning the mobs quick enough.

Biggest issues I see if tanks not using their AoE to gain an enmity hold on mobs or simply not knowing priority in their enmity combos. I do tend to see MANY warriors who focus more on their DPS than their enmity and that can cause issues.

This is not true. As a BLM I will do far lower DPS and have more missed spells if I target the same target as everyone else. A few lucky crits by the tank and a melee may kill the mob from more than half health during the time it takes me to cast Fire4.
I specifically try and pick a mob the other DPS are not targeting to keep my DPS up. I do occasionally rip a mob away from the Tank, but I can handle it by myself. Just manaward/manawall and nuke it dead while the Tank can blissfully stay doing exactly what he was doing before.

The only problems I have are slow tanks taking each mob group one at a time (4 pulls from honeycomb to honeycomb I'm looking at your Arboretum).

To that arboretum part, that's purely dependent on the teams capability, not just yours. A single mess up from a healer or tank could mean the party wipes. Those wasps do final stings and usually, right in succession. They deal out enormous amounts of damage, to the point where it simply seems like an insta kill half the time. If you don't burn the honeycomb within seconds of the tank going down, you wipe. I hardly call being cautious there to avoid the wipe (which takes more time) as bad. However, a decent tank should be able to tell whether or not their party is up for the task by the time you reach the honeycombs.
