So wasting countless gems on bad chance to get a decent girl on premium pull isn't silly, but using one gem to give me enough stamina to continue playing (and possibly get 4+ gems to replace it) is silly? I guess I could wait five hours to level before playing and thus use them more efficiently, that is true but silly? Maybe not as efficient... However in some cases I have actually gotten gems I wouldn't have that day if I hadn't rejeuved stamina...
Not to chapter 12 yet, working on getting my girls stronger... but once there I will certainly be doing the 80 stam stage for manyu hunting.
I should probably save some manyus for Lavender... 23/24 medals, think I'll leave it at that...
