Thought is very simple: we have summer, autumn and winter global event. BUT WHERE SPRING??! This really big pit with event interval can be filled with some events such as Valentine or Easter. Add some new props, new skins and loot, new decorations for map. I think this shouldn't be really really hard and scare. Moreover, players offen playing on the events, and this will be a quite good thing to add new event for spring. It is possible that such a question has already been raised, but i don't know and just wrote this from boredom)(
