>>23328867Give important NPCs (gym leaders, E4/Champion, Evil Team leaders, endgame rivals) impossibly strong Pokemon, especially for NPC Megas. Things like giving Diantha's Gardevoir 500 HP. Make boss battles actually feel like boss battles instead of extra bumps on the road.
Give all non-Ice-types -1 priority in Hail.
Acrobatics now ignores the user's Mega Stone.
Delta Stream is no longer blocked by Air Lock.
For shits and giggles: Megas now have two abilities active after Mega evolving instead of replacing the base ability with the Mega ability. The ability Inner Focus guarantees that the user will successfully use an attack read: spend PP as long as it hasn't fainted before that point. In other words, the user will be able to attack normally even while sleeping, fully paralyzed, totally infatuated, or even after hitting itself in confusion. Hyper Beam and its clones won't force a recharge turn after scoring a KO.
