Next Orianna event or similar ones too it, maybe consider tying the amount of disguises you get to VIP level.
I.e.
VIP 0 - 1 disguise
VIP 1 - 2 disguises
VIP 2/3 - 3 disguises
VIP 4 - 4 disguises
Its only natural in a F2P game you'll have some folks playing dozens of characters trying to game the system. Might as well make them VIP up or only give them one chance a day. I know you all deal with localization issues etc, but its certainly disheartening to myself and others when the same characters win the lottery multiple times.
Thanks for your time.
