I'm surprised no one mentioned FFXI in all of this. Surely someone here must've played that game back in its glory days. I experienced my fair share of DPS pulls in XI, but FFXI leveling mechanics were vastly different, in that it didn't have instanced levelling dungeons. What it did have though was a party system that was reliant on good communication.

In order for a group to get good, efficient exp, everyone needed to be on the same page. If the tank and healer was geared enough then one of the DPS could run off to grab another mob and bring it back to the group to keep the exp chain alive. If the healer didn't have the MP to sustain chain pulls then they'd have to let the others know to rest for MP.

Anyways, back on topic of FF14, because of dungeons and DF, it's rare for any kind of "planning" to go into a run, aside from boss explanations for anyone new. If your sole purpose is to speed through a dungeon then just ask at the beginning and you'll avoid any problems.
