Daily rewards for logging in. A random item gacha would work for this and pokemmo could allow people to spend RP to spin more than a once a day freebee.
Honestly I'd enjoy seeing the game corner on island 2 actually have some games in it. Rather than give another game corner that works some extra games.
I don't know if pokemmo is ever gonna add anymore pokemon besides legendaries. So I was thinking why not introduce something like alola pokemon. Whenever a pokemmo region comes out with thier own storyline and stuff have some of the pokemon which we already have be different typing. The look of the pokemon doesn't have to change though but would be a welcomed addition.
So I've noticed that they changed a few things around on the update. One thing that bothered me is that they decreased covets PP to 25. They also increased thief's PP to match covet's so now theif and covet are pretty much the same except for one thing. thief has a base power of 60 where covet has a power of 40. I suggest that covet's power increase to 60 to match thief or bring down thief's power to 40.
Should just make it so when a TM is acquired, where ever that is in game, to make it available for cash/coins somewhere else. Not like having an extra money sink would hurt anything. I see this as the easiest solution.
As an event prize I'd want a transformation ticket which turns a normal pokemon into a shiny. So you can actually choose what poke you want to become a shiny than someone spawning a shiny and giving it as a prize.
