Guild Wars 2

… to play an Arms warrior while strictly using only the rifle and the skills related to it? Pertaining to PvE of course, and in competitive terms. I wanted to try a sniper-ish character, but I’m not fond of bows (striking out Ranger) and the Engineer class seems to get too technical with the skills.

Yes, but the main drawback will be lack of aoe (excluding piercing shots). I play primarily with rifle, but I do keep a bow and melee weapons handy if aoe damage is needed.

Not to mention the rifle itself has little in the way of utility you can actually use to keep yourself alive when targeted. Rifle butt’s nice but only really useful if you’re in a large group. In small numbers think really fast because you have about 1 second to come up with something before you’re back in melee again.
