Just want to throw my 2 cents in as well.....

I agree that gping full dps stance with your own healer is just fine, but in a DF setting, why put the possible strain on a healer you don't know?

Say they are already skiddish about healing and you pull the whole first floor of balesars wall. It's inevitably going to cause a wipe. There's just too much outgoing damage from all the bleeds on all four of you. Eventhough it's most likely your fault as a tank by going dps and pulling too much, the healer is probably going to think it was them.

I'll just check their gear and ask them you say? They are probably on ps4 and geared their healer through a dps job. I'm just saying. There's a time to drop tank stance, but in DF.......Probably not as much.
