The 100% exp boost was nice coz it was puting players to play togheter to grind grind grind exp, tho it was nice seeing some lonely areas full with players i personaly want something way more bigger. I was thinking of something that shapes the world or changes the next events of the world depending on how players do. Simply as a village could or could not end in a fire or a forest could or could not be deforested, a full map can be invaded by super bosses that gives nice loot, an area that goes under water , earthquakes, thunderstorms, hurricanes, depending on how players react and succed or not would realy make the game outstanding.
PS. its 2017 where is the horse racing??
