I reported this bug through support in-game, but I really wanted to bring it to attention. The warlock talent “Backlash” is not working properly. When triggered a second time while you have it up, it removes the existing buff but does not reapply itself. Essentially just removing itself. This is a very annoying bug, and it has cost me arena games and battlegrounds. Destruction PvP is niche in TBC classic, there shouldn’t be an additional reason not to play it, especially not because of a very fixable annoying bug.
Thank you.
