I’m glad you’re enjoying the new set but there are some issues with your build:
- Rapid Fire is not buffed at all by Gears of Dreadlands and does not fire primaries when channeling Rapid Fire. My suggestion: drop this skill entirely along with Wojhanni.
- Vault shouldn’t be necessary as you get a lot of mobility with Strafe once you get 20 stacks of momentum.
- Vengeance Dark Heart and Shadow Power Gloom are much better than Side Cannons and Well of Darkness for survival purposes.
- Captain Crimson’s set requires using the Ring of Royal Grandeur (preferably cubed) and a belt slot. This means you lose out on Depth Diggers or Hunter’s Wrath in the cube which is a HUGE damage loss.
- Since you’re using Bolas (a relatively weak generator compared to Hungering Arrow with Ninth Cirri Satchel), you need to use Leonine Bow of Hashir and Ememei’s Duffel for maximum damage potential.
- Instead of the Endless Walk set (Traveler’s Pledge/Compass Rose), you could use Unity or Elusive ring for an equal or greater amount of toughness for a single ring slot and then have a free amulet slot for say a Flavor of Time or Ess of Johan.
- Nemesis Bracer’s aren’t optimal since you want toughness in hardcore, therefore your bracers should be Wraps of Clarity.
- While Simplicity’s Strength is a choice gem for this and Zei’s is an okay choice, the Molten Wildebeast Gizzard is an odd choice. Better options would be Esoteric Alteration for toughness or Bane of the Trapped for damage. A balanced gem would be Taeguk but remember that Taeguk doesn’t work with Rapid Fire for two reasons: (1) Sin Seeker’s eliminates the channeling cost, (2) Wojahnni Assaulter provides 3000% additive bonus to Rapid Fire which almost negates the benefit to the additive (up to 80%) bonus provided by Taeguk.
I don’t know where you searched but there are good guides out there such as DiEoxidE’s recommendations thread in this very forum:
