Hmm.. it's always bothered me that people would demonize tanks for having that "you tank it, you spank it" mentality since that was their way to dictate the run. But magically it's okay to dictate a run by using rescue. A little too much hypocrisy happening...

Other than that...

That skill is hardly used and when it is, depending on your experience, it always causes; confusion, frustration, or rare praise (if it was done right). For me, I have been thrown off more cliffs and into bads more than I have actually been saved. Hell, last week in Dun scathe a healer felt the need to rescue me off the cliff as they went down (didn't even know that was possible).

I don't use the skill my self because theirs no need (especially when I can just toss a shield at them). As for the pace of dungeons, from my view, wall to wall pulls are not that common. Most of the time it's like 1-2 packs that happen with pugs. It doesn't bother me when I play healer, I just simply go DPS mode. I noticed when I do this tanks feel more comfortable and sometimes try pulling more or less when they realize it doesn't bother me at what pace they go. Keeps the party in a good mood I guess, since they even start to chat. This is just been my exp.
