[2020] The concept of buying Agents is dumb

This is the first thing that bothers me i dont like the concept of you have to farm money to Buy Agents. I cant even Test the Agents in a custom game if i like them or not and if i spend 15k ingame money for a Agent i later dont like would be dumb. My idea would be you get for every Agent a Card and you can test the Agent then 24h or 12h ? should be enought time to know if you want to buy him or not. Or just make all 4 free and sell more skins so you still get money :D
