Iron crown event

I would like to know how this works it says there's 50% for a legendary cosmetic and 50% epic cosmetic and guaranteed crowns so why am I not even getting an epic cosmetic all I got was crowns after THREE DAYS of grinding for the apex pack I literally got nothing I done even have enough crowns still after the apex pack to get anything from the iron crown store this is cheesy and it does not encourage me to spend as much time on the game I'm not rich I bought battle pass shouldn't that be enough, no now you guys are expecting me pay 200$ To even just try to get one skin. fortnite isn't even that expensive I'm not wasting my time to get apex packs just so I can get literally nothing only crowns? That doesn't make sense and if you don't fix it or make the odds more fair then, Im seriously thinking of going back to fortnite at least I'm not force to pay an arm and a leg it's outrageous, I haven't played your game since cause I was hoping for something cool and the only thing I got was crowns  after three days of grinding I would like to know how that works pls asap cause I'm not playing your game if every event is like this cause if that's the case you guys are just greedy and it makes me not play the game. I spent three days straight to get the apex pack and didn't even get slightly rewarded, then at the very least I should of gotten enough crowns to buy something epic or legendary I like your game a lot and this is slowly ruining it for me
