You feel a huge hole in your skills rotation because you went Pelt1, imho Barb1 was a better choice dps-wise.
With Barb1 you have acess to Cleave, Helm Chopper and Stomping Kick (now it deals 605% at level 5 with 3 overheats, it’s not as bad as before) also with Cleave debuff, you and your clones (if Shinobi) do way more damage with basic attacks/Double Slash, same with your Corsair skill, Dust Devil or with Cyclone (if Doppel).
My Corsair used to be Sw3Pelt1Cor3Dopp1 before balance patch, then I went Sw3Barb1Cor3Shin during free reset weeks and I don’t regret it one bit (maybe Doppel1 as Rank8 would still be a better choice imho).
The only reason people go for Pelt1 is for the taunt, which is a very lazy way to play anyway… if you want a soft taunt, you can use the flag, it aggroes every monster in his circle and also takes some hits in your place, and when it’s on CD, you can simply use the secondary autos with the pistol to aggro mobs and group them together (remember your pistol autoattacks can penetrate monsters in a line, shooting the furthest away is a nice trick to aggro more monsters wasting less time).
The only other build I can see viable for Corsair3 right now, it’s Sword1Highlander3Corsair3Dopp1orShinobi, but you’ll need to have both a 2handed weapon and a 1handedweapon+pistol to run that, and unless you love going around with subpar weapons, that’s a lot of investment for a farming character.
Long story short, Swordman 3 isn’t all about PB15 and Restrain, still, you’re not forced to use Gazing Golems having 15PB.
In your case you have better options in cards purple sockets, Yekub Card (+100 holy damage), Yeti/Nephentes (more Hp or HP/SP), Rajapearl (Bleed chance) or Marnox (lol) for crit rate.
