actually, I really really dig your battle layout.
it is very, believe me, very very rare to see a great game using the original RMXP layout. With that funky window skin, it really looks cool. I like it just the way it is, especially with the fact that alot of people suffer from not having good battlers, but in your case you have access and can use some really amazing anime battlers.
My favorite battle like that? I'd say goes to southerland, and she customized hers ALOT, but it was still the front veiw 2d system, but it is like, completely customized, dun know how she did it, looks fantastic though. Not to mention she makes these seriously wicked animations, GAH, so wish I could use them >_>
ScreenMy advice, don't abandon it.
just add some custom add-ons for the battle system, make it unique, it already looks like it has quite a few things going for it, so no, I don't think your battle system should be much of a problem.
