I have this procedure to snapshot SW. First fight, I activate BoH and hit a target with 3 hits from DR for the Foresight bonus. This makes my offhand the active weapon, which is significant since it rolls much more damage than my MH. I then activate SW and keep it going for the entire duration (modulo lag issues).
Switching out the chest and/or the belt would mean having to re-snapshot after every fight, which is made extra cumbersome by how the active weapon is effectively randomised after each fight. The 75 spirit cost is a minor thing by comparison.
I could just ignore the mainhand/OH issue but that means that half the time, my SW will be about 25% weaker than normal.
Is it worthwhile for me to swap out my Inna's pieces? I'd get higher pDPS, but it seems I might lose out on eDPS. How do people handle this problem?
