If you have 330 gear, these are the most efficient ways to get to 110% accuracy and 1.3 second GCDs. With the class buff and Zeal, the alacrity threshold number is 2134, plus the 250 buffer, and we are aiming for 2384.
You cannot hit 1.3 GCDs without using augments. If you have the Zeal perk and do not want to use augments, you can go for the 1.4 second GCD by hitting your Accuracy threshold (can be done with 5 gear pieces and no stim) and then putting everything else into Critical.
