My oldest character is this monk, its almost 45 months old. I used this in PvE and in PvP, therefore it has armor which gives him 600 health, and some good equipment for pvp battles.
This is a rather new character. I have recently brought it up to level 20. He specializes in midline combat, assisting the frontliners with direct damage and weapon spells. His favorite skill is without a doubt Splinter Weapon.
My elementalist, I like to think him as a student of Zalazar Dragonsfire. He therefore currently uses the same build (and because I don't have enough money to buy new skills)
My mesmer, a pretty old character as well, but I don't like to play with him in PvE. I made him because I liked playing Mesmer in PvP so that was his goal.
