At least Brawly appears to have been seriously nerfed. Remember the latest trailer for ORAS? Well, for a split second, Brawly's Makuhita is seen at level 16. For reference purposes, it was level 18 in Ruby and Sapphire and level 19 in Emerald. And it's probably not because the ace is something else this time around, because CoroCoro basically confirmed Makuhita was still his ace a while back. Whether this is a one-off thing like Whitney was or a sign of a different level curve, who knows. Nerfing Whitney's levels did make sense, because not only was she the biggest That One Boss this series has ever seen, but Miltank was even given Scrappy and a Lum Berry as an added kick in the nuts. Brawly, however... much less so. And that's a three-level drop compared to Whitney's one. Definitely wondering how this'll all turn out.
Edit: Random suggestion. Remember how in Ruby and Sapphire, the Makuhita had Knock Off? Remember how it's now brutally powerful? Yeah, if we're going to fight that particular set I can see why they nerfed its level so much.
