I have to say though: getting my mesmer up to 30, I realize I'm not sure if I sufficiently like playing with him in a group. I think I may try another class that may be a bit more fun in a group setting for me, like an elementalist or an engineer, though I'm not sure yet.

Also, though the mesmer is definitely a workable class, I feel like a lot of the skills are wanting, so there isn't as much variety of usable skills as there are in other classes. I may jump ship and try another.

What crafting disciplines have you taken up? My mesmer is a tailor/cook. Cooking requires such a HUGE variety of ingredients and has so many multi-step crafting recipes (where you have to craft multiple precursors)...
