Gah! No! Never make your primary Mesmer. There is no reason for it. The Fast Casting attribute is pretty worthless for a Roleplaying character. Especially compared to something like the Necro's Soul Harvest attribute.

Necro for my RPing =D

And ya know.. It pays to wander around.. I already got some Elementalist powers from protecting some bird.

[Raditzu]

Yeah, especially in the middle areas, there are several quests you can pick up from people just wandering around. The beginning and ending are a lot more linear, though, and it becomes very dangerous to just wander around.

Support character is primarily Monk. If you have Factions, the Ritualist does some pretty decent support, too.

All of the classes have support to one degree or another, its just that some are better than others. Mesmers have a couple of ok support powers. Some of the Necro elites are really useful for support.

But yeah, Monk is the best support/heal. Be careful though, because Monks have stupidly high aggro.
