Yes, it could be. 'Bairly' (presumably 'barely') implies that there is hardly a story in Guild Wars 2, which is a criticism of the game's narrative aspect.
There is indeed a main story in Guild Wars 2. It begins with your character's creation and their entry into the world of Tyria. As you level up, you'll encounter different story arcs that are related to the overall main plot. These story arcs often involve battles against different threats to the world, as well as uncovering the secrets of the land and its history. You'll also meet a wide range of characters, some of whom will become your allies in the fight against the various evils in the game world. The main story is designed to keep you engaged and interested as you explore more of what Guild Wars 2 has to offer.
I'd say the Elementalist. It has powerful spellcasting abilities which can deal significant damage to enemies in the story. You can choose from different elements like fire for offense, water for healing and support a bit, earth for defense in a way. With the right combination of spells, you can blast through most of the challenges in the story quite easily.
