tl;dr The Warlock-specific item drop rates from [Otherworldly Treasure] rewards from Fel portals (‘Fel Scar’ in this instance) are terrible for a seasonal server.
I’ve run many Fel Scars since P3 started and I hit level 50 day 2. In that time, I only got Fel armor items on the first day and have never got a warlock-specific rare in all my rewards. Since then, the rate at which low-level quest rewards are appearing after portal exploration have risen. In over a dozen quests today my Explorer Imp has not returned a single level 45 [Otherworldly Treasure] reward.
The P3 best-in-slot Warlock tanking dagger, [Modas Karkun], is locked behind the level 45 rewards from this tedious explorer system that won’t even return the quest that has an abysmal chance to even drop it. There’s not even another dagger introduced in P3 that has armor at all.
Blizzard, why are you having Warlocks spend weeks of wasted time sitting at Fel portal spawns? This isn’t fun and doesn’t seem in-line with the spirit of Season of Discovery; we discovered it now let us have it.
