Below is the link to the topic in customer support of the game, there I try to create a list of warlock bugs that needs to be fixed, if you know anything that I didn’t mentioned feel free to add here in the comments or in the linked topic.
I would also ask you to leave a comments and upvotes in the original topic just to keep it running and visible. To have any chances to warlock being at least partially fixed.
The current List of known big warlock bugs. If you know more please add in the comments and I will update the topic.
1. [Warlock] Soul Well and Pact of Gluttony bug
Soul well again gives warlock a normal health stone instead of Demonic healthstone on arena and BGS.
It was fixed somewhere in the past when Warlock with Pact of gluttony would recieve a Demonic healthstone from the soul well while others get a normal health stones.
2. [Hero talents] Diabolist targeting issues of Pit lord and Mother of Chaos.
The old bug of Diabolist warlock from start of TWW returned - Demons of Diabolist hero talents - Pit lord and Mother of Chaos attack closest target that is in combat with warlock player, rather than attacking the actual target.
