How about making some Mythical Pokemons like Mew,Celebi,Darkrai,Deoxys,Jirachi,Manaphy,Phione,Shaymin etc to spawn in a particular areas according to their respective types?It would be great to do so!
So you mean mythical Pokemon spawn in areas based by their type? This would be good for players to have a few Pokemon rarer than starters out there without needing a server spawn telling you where it is. I think why legendary come from server spawn is so players don't get all the leggies really fast, so this would need to be quite rare.
