They say they added this because they didn’t like optimal play being logging out. Now, optimal play is buying a bunch of these and logging in and out and using them over and over again to maximize buff duration.
Blizzard refuses to just dive in and make proper changes. This attempt at pleasing everyone and trying to break bad metas, while preserving authenticity to some degree, is just flat out terrible. Make a real change Blizzard, stop trying to appease the small number of “No-Changers” that are left playing this game.
Stop being “careful.”
