I've played since around ShB launch. I like all the sprouts, and don't mind the lowbie dungeons from leveling roulette (apart from Toto-Rak). I try to be helpful and explain unusual mechanics (first boss in Qarn, for example).

Looking back, I wish I hadn't rushed to 80. I got to max-level content without ever having seen a lot of boss mechanics that absolutely wrecked me in level 80 content. You can catch-up on item levels and gear, but there is no catch-up mechanic for knowing the game.
