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 1494, plus the 250 buffer, and we are aiming for 1744.
If you choose this route, you should use the Advanced Versatile Kyrprax Stimulant, which gives Mastery and Power instead of Accuracy and Critical.
All of the accuracy from the proficient would be wasted in this build.
*Although this build doesn't hit 1744 Alacrity, it is still has a buffer of 191 alacrity points above the threshold. You could also choose to add another Alacrity Gear Piece and have no Critical Gear Pieces, which would put you well over 1744.
