My thoughts on PvP builds:
-System Calibrations for Alacrity seems completely worthless to me. Very rare to use a channel unless free casting
-Gyroscopic Alignment Jets should not be taken ever, IMO
-Degauss should always be taken. It saves you from melee
-Burnout should always be taken to 3 ranks
Here is the PvP build I use:
If you are fully geared out, your rapid and healing scan can actually save teammates sometimes. For this reason I have 2 points in Med Tech to reduce cast time for heals. If you prefer to never heal, move those 2 points to the next box over for +2% crit chance.
