Yes I agree, the Ability bar is by far the worst i have seen in many MMOs. I have only played WoW (for not very long), Warhammer, and LOTRO. I really liked LOTRO ability bar set up. They had the main 1-0 bar and then 4 others that you could "activate" in the options part of the game. It was really great, you could have the main abilities you used as 1-0 then maybe aoe attacks on alt + 1-0, buffs or stances as shift + 1-0 and melee attacks as ctrl + 1-0 (this is how I had my hunter set up). But you can imagine the many things you can do with a system like that. The also had the option where it would hide, or always be shown, to appease both sides (some people just like a clean screen).
