It's Gabe! I think it would be a great idea to implement the starters of Kalos region and the legendaries of Unova & Kalos. Lucario too! Those would be great Pokémon to enhance the game!
Another idea is to add more specifications to /pokegive and /pokespawn. You can add specifications to the gender, nature, IVs etc. You should only let the IV specification go up to perfect IVs which would be 13 for every stat if I'm not mistaken. (I'm kinda stupid at that stuff. )
Thank You,
Gabe
