Does it get any better?

[TouchandFeel]

A thought that comes to mind is this.

The truism that a chain is only as strong as it's weakest link can be applied here in terms of speed. A dungeon can only be run as fast as the slowest player in the group. If a tank happens not to like large pulls, or is not comfortable with them, no amount of DD running up and face-pulling mobs will help the run time. If anything all that does is slow things down even further since the Tank now has to regain hate, re-position everything and then settle back into the normal tank role.

It's quicker to optimize the run with the players you have than try to force them to conform to your demands.

Precisely, any decent tank will pace a run to go as fast as the party as a whole can go. If any member of the party is less geared, not familiar with content, etc., then the tank will take that into account and adjust down. The capabilities of the group is determined by it's whole, not a singular individual.

Not sure if it's been brought up yet, didn't see it, but one thing worth considering is that having multiple 60s means nothing at all. Thanks to Palace of the Dead getting things to that point is incredibly simple but you're not really taught much about proper functions to your job, especially in regards to tanking, healing, and any positional dps. You may very well find yourself running into people that are using leveling roulettes to get a grasp on those points after the fact.

This is so frighteningly true. The really scary part is when you run into players in PotD that fail at even being competent enough for that content.
