Mega Evolution & Other Gen 6 Crap.

I wouldn't necessarily call it simpler. Unless you find the specific hold stones for each Pokemon, you'll never achieve the megalutions. The same could be said for the form changes of previous Pokemon like Shaymin, and that rock it needs to touch, but at least those were out in the open in an area you'd inevitably pass through. Remember, it was confirmed from the official video you can't get these specific Mega Stones through normal gameplay.
