Is a level skip worth it?

(I still don't know what OGCD means, I know something global cool down) .

Off Global Cooldown, these are abilities you can weave into your rotation without changing the cast speed of your abilities. ie Sidewinder and Shadowbite which share a cooldown are not on the OGCD which means you can do your single target DPS rotation uninterrupted and still toss in AOE.
