I learned how to do it recently but my team isn't high enough lvl to do this correctly. If you have 2 rb fires with high damage then I think it's a good strategy to lvl that way so the fire can get the same exp as the water but if you are training a regular team like I am then it's not a good idea XD I tried it and my fire mage got the same exp that my water did but my damage was reduced by 1/3 since the fire was no longer attacking so I got really crappy exp x.x But I still think it's good rounds to use especially if you already have some high lvl characters.

btw are you doing the NT event next week seact :P You were pretty funny in guild chat so just wondering XD
