I don't see how TB vs RTwP is any more or less savescummy... make it so you can't save during combat in both. That's how almost every other game is.
well... okay, got me there. if you can't save mid combat you can't savescum combat.
But if you can save mid combat then RTwP has so many things going on and pausing on reload is such a pain that scumming is mostly not worthwhile. in TB you can make every attack of your team hit or even crit when you can save (though critting is also a drag to pull off each time, hitting is not. depending on the loading time a bit here)
