Guild Wars 2

So I’m new to mmos and this is the first one I’ve ever stuck with long enough to get to max level. (a thief and a necro)

Now I’m wondering what class to do next, I do mostly dungeons but some wvw with guildees.

Being new to mmos in general I want to get better at them. So I’m basically looking for a build a little more difficult to play then a condimancer, but not so much so that I can’t keep up.

So could anyone post builds they think match what I’m looking for?

I think mesmer is tricky to master and something no other game has. im not sure on builds for it though as i play a warrior. warriors are easy to pick up but hard to master.
