It may seem silly to complain about having more currency to spend, but players have been by and large unhappy with the caches of gold rewarded as an alternative for loot when killing a boss in Mists of Pandaria
. The argument does have some weight, however; and it's also been addressed before, in a slightly different fashion. When boxes that dropped from holiday bosses were viewed as disappointing because they contained nothing other than points, those boxes were adjusted to add actual items.
And let's face it -- when you're given a box of something, you really expect something to be in that box. Gold just doesn't cut it. Apparently Blizzard agreed with this sentiment, and the caches, deemed "failbags" by some, have been adjusted on the PTR to offer something far more substantial, according to a post by Bashiok on the official forums.
The change is still in for the failbags to ... not be fail. They'll have a chance to contain things like very valuable grey items (essentially randomizing the gold you get from the bags), LFR versions of non-boss loot, Spirits of Harmony, consumables, pets and mounts, and... maybe some other stuff I forgot. Lots of things! Opening them should have some anticipation and surprise now. :)
Trash drops, consumables, pets, and mounts? Count me in. This change ought to make getting that cache of items a heck of a lot more appealing to players. After all, if you get a surprise box of goodies, it ought to be full of fun!
