i like your idea behind it :)
but the rewards for UU & NU are trash (imo, sry to be rude)
like:
why shoud i choose this? it saves time of course, but i do it by my own and sometime i can find some items for $$$
the next thing is... let me say your current rewards are finally and they will be implemented so...
why should i play UU or NU maybe for SIlver Bottle & Gold Bottle
if the possibilty exists that i can get those rewards (with luck) of playing OU
also the rewards of OU are cheaper, where those bottles are than the NU rewards
*i hope my english is understandable*
