I must say seasonal Raids are indeed a cool idea. The circus raid and the Halloween Train Raid would be a nice thing to look forward to.
What I liked most about your ideas is the good and bad list for the Christmas event and I will personally alert the Game Designers to think about it. That is a very good mechanic to battle the toxic people and the gankers.
Good stuff Kashjir š
Players rating other players is a very bad idea. Mob rule usually doesn't end very well. I also don't believe there's such a thing as "toxic" players. People should be free to play how they want within the games systems. Allowing players to manipulate those systems against certain play styles with a voting system just encourages a min/max herd mentality that will destroy a community.
I do like the idea of seasonal events. October Beer Fest anyone?
