Is USUM's level curve based on use of the Exp. Share or without? I'm just wondering if I train a full team of 6 and then some without using the Exp. Share if Poni Island going to have that ~8 Level spike again. I swap out Pokemon when I find more interesting type replacements (I'll pick Rowlet but box it when I catch a Morelull for example), but I want to avoid having to deal with being disturbingly underleveled for spreading experience points too thinly.

Turn it off, y/n? Advice?
