Or you can stop blowing smoke up everyone's arses.
Four hits, 100% STR WSC, fTP transfers across all hits. Absolutely ZERO attack bonus.

Assuming off hand weapon you have 4+1 hits. With gorget / belt you get 6.0 of ftp (+0.2 x 5).
Rampage is 5+1 hits 30% STR WSC and can crit. It's first hit is only 0.5 fTP but all other hits are 1.0. With DW you have 6 hits for 5.5 fTP. You'd be using the rancor gorget over anything else, and the Attack +15 / Acc +15 DA +1% on the waist. So 6.0 vs 5.5 fTP for 9% more fTP, up to two DA's can proc to further reduce the fTP difference. Now here's the kicker, Rampage can crit and your going to get 2~3 crits on average. Those crits are what bring Rampage's average damage inline with Ruinators, especially on T+ targets when your not capping ration and level correction is being tossed in.
Ruinator is just a more consistent Rampage. And when you have limited choices, spending one for a side-grade isn't very wise unless you have no other options.
