At the start of every low-level DF run, I usually break the ice by greeting everyone in /p chat, then stating, "I'd vote for a full clear for the XP, but I'm willing to go with whatever the party wants." Most of the time, this will prompt others to speak up their own votes for the full clear, and that's what we do. The occasional times that someone objects, I don't make a hassle out of it; we still have fun, and I still get a decent amount of XP for the run.

And when I run my daily for myth as a tank, it's my privilege and joy to give low-level players an awesome run full of XP. The extra few minutes I spend fighting additional groups and clearing optional rooms are some of the happiest moments I get each time I login.
