For future events, i think there should be like a tier system... collect a certain amount and you'll get this reward. What I was thinking was that I think there should be an easter egg event similar to valentines, you collect eggs and a certain amount of eggs give you a certain reward rather than just doing whoever gets most collected or top 10 wins... this gives everyone a chance to get at least one reward from an event. You could do daily challenges too for this event to get more eggs etc. Also I would like to suggest a weekend or something for like a X2 Mcmmo levelling XP, that'd be really cool.
