talking from my standing as f2p and high level 2k cps for 1,1 k power is definetely worth it i spent as well and got a good amount of power from myoboku oil since is a new function for us and its now the best way to get some power.... also to get so much oil from an event , it will be definitely rare in the future to have such a chance!!!P2w have better chance to get it because of the rebates where they can get it but for us doesnt go that well :'D
