Blizzard wanted to KILL Affliction/Warlock as one of the meta specs for raiding AND m+. You think they don’t realize or understand that talents are broken? Of course they do, but they’re only going to fix them when the population is low enough.
Having drain soul linger there in that talent row uselessly feels just like being mocked. “Remember how cool shard sniping was in Legion? Here, come on, take it and you’ll do less dps than without chosing a talent at all! Mauahah!”
One of the things I like less of this expansion is how things that should be talents/glyphs (thus easily interchangeable) are azerite traits you can’t choose. If azerite traits were simply small damage buffs it wouldn’t be so bad. But they have a huge impact in the playstyle, and playstyle should not be decided by random drops: it should be a choice given to the player, even if the final option is obvious and cookie cutter.
