Refunds

Why do we only get 3 refunds? I personally think that is unfair, i spent all of my refunds on sona corki and fucking teemo. When i didn't know there were only 3(i was new) maybe it could be 2-3 refunds every season/year or something? or maybe you could even BUY refunds? 3 refunds is a pretty stupid idea. Like think about it, your friend's introducing you to league, and they say"Anyway, if you dont like this character you can refund them and get back the exact amount you payed for them whether its IP or RP." Noob: "WOAH thats so cool so i can like do that what 5 times every month or something?" Friend:"No you can only do it 3 times" Noob: 3 times a month?" Friend:"Nope, 3 times period." Noob: "......". I'm just saying maybe they could expand the refund token idea, i've messaged riot twice about this and my replies never answered my questions like "Why don't you do this" they just avoided the question and said something like "But i'm glad you enjoy the game enough to buy champions and skins for double the fun!" -RitoMessageBot
