You need only most base understanding of the game, typing and some grinding to beat it while having fun, then that's what most probably are going to do. If EV/IVs and natures mattered more compared to LV, to the point that it makes a palpable difference what you're grinding on, probably more people would notice the difference in normal gameplay, cause as it stands by the time those would matter, your mons are almost finished anyway.
As it is right now the only place those things really matter is competetive Multi, and and competetive MP can go suck Exeggutor nuts.
In short, those mechanics need more bang for your buck to make them enjoyable.
