I think that an exp boost is better than a level becuz when your pokemon reach max level the game drops from japenese mind trap to garbage bin junk!
I believe that rare candies should be stupidly expensive so much so that they arent worth buying. You will get people with stupid amounts of money buying loads.In my opinion there should be a set amount per player or none at all..
I'm a fan of the Rarecandys, but i think it will be a little unfair if it is easy for players to receive them. Maybe you can receive them as a reward of completing certain quests? And of course not having the price to buy it too low.
Not totally as rare candies do not really benefit a pokemon besides raising is happiness (that's what makes it level up, or so is the reason behind the rare candy it seems) and its level. EV (or EP) are not raised that way. But sure, they could be turned into an EXP giving item rather than leveling up item.And tbh, I'd rather have the rare candy un-tradable, un-equipable and have a really low market price, 1 poke maybe. Prevents abuse of collecting rare candies, and trading and the user is already at a loss as compared to another who's doing real training.Only issue, is that the EV (or EP) system is yet to be confirmed from the balance team...As for the black market and fake rare candies, yea, why not. Could do something about it.Those are my 2 cents.
