New moves with SSJ?
LOL i didnt even know moves got added/taken away when your turn ssj. So this probably means vegeta won't have FF until he goes SSJ.
EDIT: Oh yeah trick to winning power struggle against higher pl opponent is to not give them time to shoot a fully charged beam at you.
Ex.
If you are charging your beam, then all of a sudden u see the stronger guy charge his beam, then just fire at him before he has time to charge it fully. Although, this won't work all the time (depends on difference in pl), it will give you the edge sometimes.
Think about it Stronger guy w/ minimum powered up kame hame ha, against Weaker guys fully charged galit gun. The weaker guy has a better chance at winning the struggle.
Edit 2:
This might sound cheap, but who are we kidding here. Do you really expect to win a power struggle against someone higher in pl than you in an even beam struggle? I don't think so. Basically you just have to know when to struggle and when not to, otherwise your just fighting a losing battle and gaining no power.
