I've enjoyed leveling my healer with trusts to get her to 80. Now I'm using them to level my rdm. It's a bit slow and I hope it gets an experience buff given you can only level part of the group at anyone time. My RDM will hit 80 tomorrow and my trust isn't quite 73 yet. I'll start another role there soon and hopefully by the time i have all my roles leveled my trust will be 80 again.

By the way I'm only running one trust dungeon a day and doing roulettes for the other leveling needed.
