lets say u lvl 65 on barb u already made ur vit life bar up high and want more stats on str...if item like token takes 1 stats away from something so u can add it too something else like str...or in a hurry in cata and make a mistake clicking dex when u wanted to click intel.if token u can redo the 1 stat...be great if u could go all vit, then when lvl 60 move all to str and keep life....just idea for new item on ls...think it would be wanted item...
