complaining about the wheel event is a huge waste of time. Its the same wheel and they brought it back after the weekly events, clearly they realized theyre not giving us enough each week so they just tossed the easiest thing to add, wouldnt be surprised if a recharge slot machine pops up later too.
So its not that they are milking KONAN. Who btw people love (if its free..i mean konan or animal pain?? who you want?)) But its that they are to lazy to switch the ninjas on the wheel.
