Push the Advantage should give 1x advantage IP. For extra hilarity remove the +3 advantage requirement, so you can actually *lose* IP if you mess up and use it when you have negative advantage. I think this move needs a buff because it's pretty lame as it is, I don't really see why you'd use it instead of charge or dash. Buffing it in this fashion would also make advantage scale a LOT more important, which IMO is a good thing, currently IP is too important compared to the other variables.
Seize the Day should give 1/2 rather than 1/3 advantage. This move is awful when you consider that it's pretty hard to use, and often leads to standing around with no move queued. Making advantage more important with the Push the Advantage buff would make it a lot better, but I still think it can use a bit more love.
Float Like a Butterfly should give the enemy defence or cooldown reduction instead of giving IP, as giving IP is practically suicide.
Feign Flight should have cooldown same as Charge, so it's actually useful in rare situations, as opposed to being useless in all situations like it is now.
