I am playing on the newest server and we dont have shinobi fist or hammer event which are p2w. I want to try my luck on with 100 gold top up but since we dont have the events I dont see why should I top up.

my question is when you dont collect rewards from events the system sends them in your mailbox. if I top up and cant pull, will the system will pull it for me and send me the rewards in my mail or the 100 ingot will go waste?
