So, are you saying that the stats from using pve weapons more than make up having an expertise cap 82 points lower?
In some cases. The issue is the hits. The Forrce/Tech is higher in some PvE hilts, in addition to the Power/Main/END increase. The 82EXP is only about a 1% loss in damage from EXP, whereas the gain is around 4% in damage from those.
On a side note, weapon damage classes/specs should be using a PvE build like 72/69/58 because weapon damage is still broke.
