Mass pulls: don't do this.

[Gorlioliolio]

Your job as a tank is to get and maintain the attention of a mob, and only letting that attention go in the event of things like tank switches, or if agro is simply impossible to establish due to a fight mechanic. If a tank can't do that in the face of Regen, Medica II, or Fey Covenant, then go back to the pre 50s and learn your job again, or seek help from someone who knows the job inside and out.

You obviously have never played a tank (I read what you said but really? I mean seriously?) because anyone who has can tell you that initial agro automatically goes to healer if the tank isn't smart enough to click off regen/medica 2. It's easy enough to pick back up but advocating mass pulling with either of these going is just plain stupid.

Also, you can drop buffs like regen, medica II, Fey Covenant, and even Stoneskin and Protect off your bar early by right clicking on them. I suppose that might be ANOTHER benefit of playing an MMO on a computer instead of a console though.

You did read the part in the OP about regen mid pull right?

Also paragraphs... enough said.
