So i just got past the 8th gym, and will be challenging the elite 4 soon, but seeing as this game is vastly different too all other Pokemon games I've played, I've noticed im going to need a party of 6 around level 80? is that a must need? and it just feels like it takes soooo many hours to get that amount of exp at this point im just really eager to get to johto and catch some of my favorites :/ any advice on the elite 4?
