Literally the most basic rotation for Sabo/Engineering spec. I do not use roll, quickshot, charged burst, or fly-by (except opener) in this rotation. This rotation is to help people, whom have never played the spec, get a basic feel for how it plays before trying to add anything extra in.
Gear-wise, I have all 192/198 set piece gear with low endurance/high power mods and enhancements. I run two enhancements that have alacrity and have a 24.5% crit chance. I am going to try some other gearing options with lower crit rating but, so far, these stats have been doing pretty well for my overall rating. Using power augments over cunning gave me an increase of almost 350 DPS.
This spec is great but it is very situational. I choose not to use it for Torque, Underlurker, or Revanite Commanders and, instead, use Sharpshooter.
