We'll I have around 20 crux crates nothing to Do with. Why not if ure on winning team u get a crux chest Support below
Dark haven is right not everyone wants crux chests because they could get building tokens or whatever else they are looking forward too.
you get the crates by doing what you normally do. one free key every 24 hours is the real reward. and if you really want to reward yourself then spend a few dollars.
12 hours would be more appropriate. considering the duration of the event, the chests would definitely stack up. this would help those who wouldn't pay any amount of money anyway, even if you only got to open one chest the whole event, and it wouldn't effect those who open 10 a day with picks.
