I don't want adept variants crowding the pool. That's me. I want shinys for the Glaive, SMG, and sidearm for the overflow origin trait. And if you're a PvE player like I am, you should want the best odds to get the best rolls. That's normal CoB. By the numbers. The one exception is adept impact for the Sword which is a Nether weapon. Yeah, I made you suffer through the statistical reality 😜. You don't need 13 for Expert CoB. It's a crude skit by Tenacious D. "One is all you need". The loot is the same, you can solo farm Expert CoB... always could. You're welcome. I'll be playing normal to exclude adepts to get my drops. 😇👍💠 Get the boss one shot. Wait. Kill. Rinse and Repeat. Boring, however for the time being... the odds are the same. Only a few minutes slower because you can't finish early.
