The managers always say there will be a new in-game system to get content right?

so here's what i thought of:

a system that consists of 'free tokens' , 'shards' and 'free crate rush'

About 'free tokens': this is a thing that you get every month (only for F2p and little spenders), maximum 30. the number of free tokens will decrease by 1 for every $0.5  you spend in the month. so those who spend over $15 will get 0 tokens. You can also get an extra token every event you complete( battlethon, specialization spree) in the month if you at least get 5 tokens in that month.

About 'free crate rush': this is a thing that appears for 5 days every month after the tokens mentioned above is given to us. Sometimes it'll be acoins, credits and fortune keys(750,1250,2000 acoins, 10,15,20 keys, 50000, 80000, 100000 credits per 10 tokens), sometimes it'll be shards for content that hasn't been bought( 15 random shards per 15 credits)

About 'shards': you can get the content if you get 40 shards(epic) and 60 shards(legendary). after that you'll get 3 blueprints(epic) and 1 blueprint(legendary) for every shard you get.

How's my idea? how can i improve it?
