Is this typical tank behavior in DF dungeons?

You're post sums up whats wrong with the community.Just because you're in a lower level dungeon and all synced level doesnt give you the right to show complete disrespect to the tank regardless if you can handle the mobs without a tank or not.
You were being impatient and running ahead of the tank on purpose by the sound of it.
Most people dont check peoples profiles on runs unless there is a problem arising from low dps or heal or tanks taking too much damage.
By running ahead of tank on purpose you are setting a bad habit that newer high level players will adapt and in turn do to new tanks.
I suggest you go back and learn the basics.Rule 1 tank goes first.

There were no newbies in that run and the tank for whatever reason was moving unusually slow. Me the other dps and the healer were moving ahead of the tank because of that, this wasn't just me acting out. We asked the tank to move faster and she responded by quitting immediately. I'm sorry but I've also tanked and duties are a team effort and if the team requests an increase the pace of the run, quitting instantly instead of asking us to slow down was not the polite thing to do. The quitting penalty exists for a reason. I'm sorry if you feel I'm what's wrong with the community.

If they were moving slow and they dsiconnected it sounds to me like they had connection issues or lag.
Also plenty of level 70 players are new.The way leveling is now your character level doesnt define how new you are anymore.Also i never said specifically the tank could be new.

Usually it's the polite thing to do to tell the team your lagging or having connection issues, instead of just instantly quitting because the team asked you to move faster. And no, she did not disconnect, you can tell when a player has quit a duty cause their portrait disappears.

Not everyone has a keyboard.Stop looking for excuses to make the tank look like the bad guy.

I see no point in continuing this discussion.
