The chest at the end of Obsidian Sanctum is still account bound. It was made that way a while ago, when frequently running the Obsidian Sanctum was the best way to get badges, compared to the abysmal rate you got them through standard WvW play.
Thus, topic title: why is it still this way? It’s incredibly easy to farm badges the ‘proper’ way now, between ranking up providing a fairly meaty amount of badges of honor, and EotM existing. You also get them by the truckload in achievement chests.
Would it be possible to get the jumping puzzle reverted so that you can do it several times in one day on different characters, seeing as the original reason it was changed is now defunct?
