As mentioned in the Miracle thread, I'm tweaking some Pokémon's movesets, typings and abilities to make them more interesting and unique. The Pokédex is getting quite big, though, so doing this on my own is getting hard. So, I decided to make this thread in order to discuss the tweaks and hear your ideas!
The point of this thread is not to make everything game-breaking, though. It's just to give Pokémon like Ledian a niche that makes them worth using and make your options more diverse. There will be some rules, then:
1) Unless the Pokémon really needs it, try not to go overboard with the stat changes. A +10 raise is enough for most Pokémon.
2) Keep your changes reasonable and flavorful. Fairy Mesprit is fine, Hydro Pump Vivillon isn't.
3) Remember, those tweaks are meant to increase diversity! Try to avoid saturated niches or changes that make a Pokémon so good it overshadows everything else. No Aerilate Noivern, please!
4) Keep other forms in mind! While vanilla Mawile is weak, increasing its stats would affect Mega Mawile.
5) Most of these rules can be reasoned with if you can justify your choices. Buffing Gyarados is unacceptable, but giving a large stat raise to a Pokémon like Delcatty is perfectly sensible.
