Polished up my build a little and ended up with this. http://www.torhead.com/skill-calc#801hMhMZMsZfIzrzhhM.1 There were a number of posts discussing the effectiveness of Shield Rate in PVP and the verdict is that Tech and Force attacks could not be Shielded, got test it out yourself. Therefore, the purpose of this build is to maintain a certain amount of "Thickness" with Rebraced Armor and Soldier's Endurance. You could easily run in Ion Cell instead of Plasma for the 60% armor boost and Guard with a potential to switch to full DPS-mode with Plasma Cell after getting the medals associated with Guarding. (I usually get most of the Guarding medals within 5 minutes of the match) Your main dps will come from juggling the awesome 90% Armor Penetration HIB and ammo management will largely come from High Friction Bolt and Ionic Accelerator. Late game gear will focus on Crit and Surge to pump out even more devastating DPS. TL;DR Shield broken, points better used on increasing DPS in PVP
