Archers are popular for a reason, but are the squishiest DoW's.

On THM there will be a lot lot more to do than nuke as you rank up. If you want to be a mage and not be on healing/buffing duty, this is your best bet currently.

IMHO Lancers have some really awesome looking moves, the ones I always pause and "oooh" at. xD I haven't played one but I regularly party with a couple and they are pretty awesome.

But if you want to be more "durable", I'd suggest trying Pugilist or Marauder (which can also tank).

As the others have said though, you can just try them all, and pick up some useful abilities in the process! Good luck!
