Healers who rescue pull tanks into mobs.

[NessaWyvern]

I don’t have rescue on my bars as a healer, and single pulls don’t bother me, but that being said, if the healer is making you pull, then you probably can pull more and be fine. It’s a tanks role to pull and hold aggro, they have more than enough defensive CDs to handle two or more packs. If you only pull one pack at a time, you don’t even need to use your defensive CDs, which are like 1/3 of all your buttons as a tank. That’s like a DPS who only uses half of their rotation, or a healer that doesn’t DPS when everyone is at full HP and safe.

You’re only partly doing your role, so you are probably making the healer (who generally plays healer to you know, heal, and not spam holy/gravity/Art of War the entire time, which is what happens with single pulls) a bit mad, thus the rescue pulling.

Edit: After reading this thread, I am going to add rescue to my bars
