>>50874111>The issue is that doubles and normal battles require entirely different strategies/movesetsOkay, so change out your strategies and movesets with your infinite TMs and infinite move tutors and loads of great items. This isn't base Emerald, it's a QoL romhack that expects you to use those resources and more to the full extent.
>there's no point redesigning your team for those scant 1% doublesThis is a non-example you use only to make your point. If a decent chunk of battles in the game are doubles like in a lot of these hacks then clearly there's no issue.
