yep. You burst in the same way that you did before you rb'd. The exp won't be the same though. I think the exp is only around 200 or so per battle (I think -.-) The only time bursting with a water changes when they are rb is if you rb your water as a wit and you decide to get the wit JS skill cuss. Then you use cuss instead of shrink so your damage dealers can cause more damage and the characters you are lvling up will get more exp. But your water will use a lot more sp per battle.
