Your math doesn't add up, at all.
Inquis went from getting 50% of their doubleshot score ( whatever it is ) to 100% , that alone is twice the dps they had. RXB went from 33% doubleshot to 100% which is three times as much dps.
so (meta) inquis went from 130 to 150 DS.
post update:
150% DS = 2.5 multiplier (on average)
pre update:
130% DS x 0.5 = 65% DS = 1.65 multiplier (again, on average) (51% more dps)
it very clearly did not double, and it would only double if you have infinite DS.
repeaters went 100->130 (roughly)
100% DS x 0.33 = 33% = 1.33 multiplier
130% DS = 2.3 multiplier (72% more dps, very clearly not tripled)
I dont have the number on repeaters but inquis went from using 210 bolts/min to 160 (using 2 fusilades), which is a 24% loss. Multiplicatively
1.51 x 0.76 = 1.1325 or 13.25% more dps
I recommend showing why math is wrong rather than just feeling/guessing what the answer is because it makes you look like you cant contribute to the discussion.
