If this gets fixed, then PRO will only become a better game because of it. I agree grind is inherent in MMO's, but Pokemon was already a grind if you don't have thing like egg exp or traded exp and the like. All we have here mostly are wild pokemon battles to level up with and that process should not take forever. Imagine repeating it over and over if you were a competitive player simply because you wanted to add a new mon to your roster.
ON top of that, just the fact that there is no breeding alone (which I'm fine with) means there is addtional grind when trying to get a good natured/IV mon.
