Well for me all my main offensive skills are on my first 16 set cross bar so 1, and then all my defensive skills are on my next set of 16 so 2. Then my set 3 is just like mounts and tele stuff like that. What I am say any yes I know you can press R1+ square and all that. BUT it would make it much smoother and easier if you could just press R2+L2 since they are not mapped to anything anyway to pull up another set of 8 skills without having to flip your skill sets. Think about it the reason a keyboard is much better for one is they don't have to flip to anything its all right there, and if not they can quickly get to the skill with their mouse. As for us we may need to flip the bar to another set of skills use the skill then quickly flip back to go back to your main rotation.
