Currently, you can only get the perk to host a certain event from seasonal crates (such as the Christmas crate). However, I think that the Event Crate should also allow you to win events. Except, you can only win one event, and this reward is extremely rare. Say you win Wool Shuffle and get an Event Key. The only event you can win from that key is Wool Shuffle. If you win Redrover, you can only get Redrover from that key. This goes with all events. It just makes it so you don't have to pay a lot of money for a low chance at getting events... instead, you don't have to pay to get an extremely, extremely rare chance. In all seriousness, I think it would be nice to have, as people who won't have to spend as much money to possibly win events. Maybe this would balance things out some more.
