If you haven't started the final episode, it made short work of getting Ventus to lv99. If you're already in the final episode, you're likely doing the best thing there is (since I don't think you can hit up RG without engaging in boss battle action then). I went with a largely defensive build for Aqua since that battle was darned rough.

I tend to put down tough games and come back for revenge, but I feel similarly about trophies. If the throwaway/should be easy trophies take forever and a day to get, I consider that unreasonable. Got to be a balance of challenges rather than things designed only to sink time into. I don't mind that for some, but geez.
