Ok this question is for the Gandiva users. I know Vulcan's is better for gun due to fire affinity however my question is this -
Why do so many (if not everyone) I see with Gandiva use Vulcan's over Jupiter's staff?
We are basically looking at +10 R.Attk vs. 15% Crit Hit Rate.
On paper (as I am yet to parse this) Jupiter's with fairly standard gear will increase DPS by about 10%. If we are talking purely overall bonus, vulcan's staff offers (from my terribly rough math) a ~1.3% boost in R.Attk for a lvl 90 RNG (Due to a lvl 90 Hume RNG having about ~820 R.Attk). Yet Jupiter's offers a solid 15% boost in crit hit rate.
So in *theory* Jupiter's is a stupidly overpowering main hand boost compared to Vulcan's..
What am I missing that Vulcan staff users know about?
