For example, one Guild Wars 2 warrior might decide to build his character around gradual damage which causes his opponents to bleed out, while another may choose to knock his opponents down, controlling their movement with slow, large attacks. Both warriors can choose to equip the skills that matter most to them. It is also very important to us that our skill system be simple to use, leaving the screen as clean and unintimidating as possible. All of this combines to give us a skill bar and skill system that's a bit different than what you'd typically find in an MMO.
