Skill Speed and Warrior

[Alphras]

If you have enough skill speed you can double weave Inner Release and Berserk and still get 9 GCDs in your Inner Release window. I am talking about using Inner Release and Berserk in the same GCD, sorry if that wasn't clear.

The problem with a 2.5 GCD is that you cannot get 9 GCDs into a 20s window that way, which the WAR "rotation" builds upon. So the most important parts don't line up.

Edit:
Maybe I should clarify this more, since I was assuming this was general knowledge.

The ability of double weaving Inner Release and Berserk enables you to perform the 6 FC + 2 Onslaught + 1 Upheaval window from any point in your rotation after a Storm's Eye (if you are at 100BG). If you need to use these cooldowns separate you either need to start with the GCD after Storm's Eye (very inflexible) or you need to drop an Onslaught, since you'll overcap.

The disadvantage is of course having more Skill Speed.
