RP, no. Adventure... technically also no, but you'll rarely find someone who manages to make a dungeon run enticing when it becomes a spectator sport. By and large, the best times I have are when I'm adventuring with a group with a similar power level (which sometimes corresponds to actual level, though not as often as I'd like) to my own, and can RP as someone who's actually materially contributing to the adventure.
It's part of why I'm so sensitive to the server's questionable balancing: It blurs the already thin line between grinding and adventuring.
