I've done some testing using both builds, and have been finding the best results with this build so far:
DPS: 2409.91 (Cutting off the points where bleeds are wearing off on the dummy at end of parse)
Build: 8/22/16
While not exactly tactics, this is using a derivative of it that combines features of both tactics and assault.
Currently, I am in pretty much all lvl 69 gear (no set bonus) minus the weapon barrel, boots, and one relic. I have some blue 26 aim augments currently and am working on getting the more expensive ones. The gear is not perfectly low endurance optimized yet.
I ran this parse without the sage buff at the time.
Aim - 2922 (no sage buff)
Power - 770 (799.6 bonus damage)
Crit - 360 - 25.37%
Accuracy - 283 (98.06%)
Surge - 432 (72.06%) <- need to switch this out for accuracy.
Alacrity - 0 (haven't tested yet)
Skills used: Ion pulse - to build stacks for pulse cannon
Plasma Cell: Necessary to get HiB procs, plus the burn
Pulse Cannon: Whenever 3 stacks are up, and high impact bolt is not available
High Impact Bolt: whenever available
Gut: When bleed wears off
Incendiary Round: Only when ammo is available for use (If used in my rotation my ammo management would get screwed up quickly)
Stock Strike: Use when you have a free stock strike to proc HiB.
Also was using my 154 aim reusable stim, proc power relic (510 power), on use Dread Guard power relic, and my rakata attack adrenal.
