im pretty sure u dont have to put the excact mod back in its original place.Just put one with the same stats.Im mainly a PvE player and in my rakata head i havent keep the old mod so i bought a BM piece with the mod i wanted and switched it back.
Is there any for Defense Guardians?
I mean one with all the details on where to get what and what mods,enchans to use or swap etc.
P.S i mean Operation list not pre-operation
