It’s too late, GW2 is watered down so everything is set in stone and there’s no customization available, they focused so much on the marketing of the game to make it “revolutionize” from GW1 that they ignored the core game play. It would take way too much time for them to add new weapon skills for every class + every weapon and balance them when they are incapable of making it balance even with the current available skills, due to a lack of the holy trinity system thus everyone in PvP just either bunkers or fails.
