Well, I won't be saying much because much of what's been said are true.

You're the tank, you decide what speed the run is. But at the same time, you also have a responsibility to decide what's best for the team.

I mean, I've been speed running everywhere since I got my Ragnarok but when you have a fresh 50 in AK with a healer that doesn't know how to use his buffs, I won't pull the entire level down on me. But if I want, I can. But does that make a fun experience for the healer? No, it doesn't.

Size of the pull depends on the tank. The duration of the pull depends on the healer.

If the healer can't heal you over the damage you're getting, you'll wipe. If you can't handle that much damage, you'll wipe. So balance it out.
