Guild Wars 2

Wow, i didn’t expect so many great replies. Thanks a lot all of you. I’m thinking guardian will be the best bet. I have always been kind of turned off by them, but after reading some posts they do actually sound exactly like what i was looking for. I think i will leave Mesmer as a side project for now, as i am very intrigued by them. I have to go to work soon, so more reply s are welcomed. I will make my decision when i get home haha :P

Hey guys, ive been playing for about a month now and have just recentlly got my necro to level 80. It seems like a great class but my main focus at the moment is dungeons, and i just dont feel like i am very important to the group.
I have been debating between Mesmer (which looks most appealing) Warrior (because lets face it, they are hyped up a lot) and a guardian. I am also considering a Ele but idk.
Some basic info about my play-style would be
1. I consider myself a somewhat skilled MMO player so a complex class isn’t out of the question.
2. I like feeling like im helping the group im in a lot, rather then just being in the background (but still helping)
3. I like DPS or “Tanking”, as a necro i am built as more of a healing support type character, and healing just isn’t my fortay. I don’t feel like it is as needed in GW2 as other MMO’s as all class’s have their own pretty good healing ability’s.
4. I like leading a group and being important.

I really cant decide between these class’s and im just looking for some more insight. I plan on doing a lot of “dungeoning” and fractals. I am looking for a solid class that will contribute a lot to the group, and even possibly help carry a not so good group. Any insight or advice would be greatly appreciated. THANKS
