Agreed. Accuracy is my main concern with BRD - as I only use Naegling/Cento or Twashtar/Cento combo (Never use Carn for DPS).
This is the set I'm using currently and didn't have an accuracy issue in Sheol C
ItemSet 384019
Bunzi's: R25
Linos: 15 Acc/Att, 3Quad Att, 4 Store TP
Waist: 20 Dex, 30 Acc, 20 Att, 10 Dual Wield
Telchine Legs: 10 Dex, 20 Acc, 6 Store TP (plus the 3 base double att)
Chironic Feet Augments: 13 Acc & Att, 3 Quad Att
As for Reiki/Eabani combo. I personally think unless you have Volte Tights it's too big a compromise to have to make up the haste with a leg piece with no multi attack or store tp stats.
Interestigly the spreadsheet with the above set but swapping the legs for volte tights, and the waste for Reiki Yotai & cape for double attack, keeping the Cessance/Telos gave a slightly higher dps than swapping one of them for Eabani.
I generally prefer to test things out in game though. Omen is a good option because it's the same mobs with no competition; albeit relatively low level apart from the Transcended.
