1. Make it so the auto-weather pokemon's weather dies out once they switched out or fainted.
Are you trying to kill weather teams off? That's not very good for reasons that are obvious: getting rid of SS, Sunny Day, Hail and Rain Dance teams isn't something I want to see leave, I want more options open! Maybe a total of 6 turns or never (like it is now).
2. Add an acid rain weather effect. Have it damage non poison pokemon every turn like sandstorm does. Also increase the chance of poisoning by like 10%
Not too bothered.
3. Give Flareon flare blitz
Would be a cool BL CBer.
4. Give Blaziken Close Combat
I'm sure he needs it.
5. Give Snorlax slack off
Yes, yes and more yes. I want this Pokemon to have this move. Not only will he open a wide viriety of sets, etc. He fits the role of using the damn move, being lazy.
6. Give Empoleon roost
Why? It's random if you ask me.
7. Evolve pinser, rapidash (maybe a pegasus like pokemon?), Banette and Tropius
It would be cool.
8. Give Dialga, Palkia and Giratina their own unique abilities (pressure is overused)
Then why not the new ubers to come?
9. More rapid spinners
I agree, this generation (metagame) has hurt the best quite significantly.
10. Make a never missing ice move with good base power
Ice Beam is one of the best moves in the game, satisfied?
