If you have 336 gear, these are the most efficient ways to get to 110% accuracy and 1.3 second GCDs. With Zeal, the alacrity threshold number is 3209, plus the 250 buffer, and we are aiming for 3459.
A strong but expensive option, this build uses 6 Gold Augments.
Another good option, this build uses a ton of Purple and Blue Augments.
Very similar to Option #2, this choice uses one extra augment slot to allow for using only Blue Augments.
Due to the 2 Critical Implants, there aren't many options for hitting 1.3 second GCDs.
