This is my go-to choice. You have relatively low wasted extra tertiary stats, which means a whole lot of Critical Rating!
While this option actually gives you 79 more Critical Rating than Option #3, it involves a whopping 6 Purple Augments, which costs quite a bit.
This is another good choice, although most people prefer Option #1, which uses the Advanced Proficient Kyrprax Stim. This gives Option #1 394 more critical rating, but this option gives you an extra 264 Mastery and 109 Power through the use of the Advanced Versatile Kyrprax Stim.
Normally there is an option for mixed gear sets, purple augments, and no accuracy stim, but as it turns out, using purple augments in this build would not lower the number of augment slots taken!
If you find the cost of purple augments prohibitive, this may be your best option. Remember though, what you don't spend on purple augments, you will still have to spend some to buy an extra blue augment. As you can see, you waste a lot more Accuracy and Alacrity that don't give you anything and lose some Critical Rating, but not too much.
Only netting a loss of 79 critical rating compared to Option #4, this option uses less augments on accuracy - so if you aren't planning on augmenting every extra slot with critical rating, this would be a more cost effective option for you.
No builds with a single gear set and no accuracy stim allow you to meet the accuracy and alacrity thresholds.
