There are 8 professions in Guild Wars 2. The one pictured is the Ranger. The ranger is the master of the bow... and the greatsword??? It's true, the ranger is a jack of all trades you could say. They are deadly at range with conditions and explosions and traps. And just as surprising at melee with dagger and sword to cause bleeding and stuns and knock-backs. No matter the battlefield you happen to meet the ranger on, they are prepared to match up no matter what the challenge.
There are 8 professions in Guild Wars 2. The one pictured is the Mesmer. The mesmer has the ability to conjure copies of itself, create illusions, cause conditions, and create invisible walls and such. They are a ranged based class. You can equip a greatsword, but it becomes a ranged based weapon. The illusions the mesmer creates are actually good in PVP because they look exactly like the original and behave like the original. Mesmers can confuse real players.
