Upvote if you want 1 refund per season OR a champ/skin testing mode.
We've all been there. Refunded a champ we bought for IP because we were too noob to realize that it was a bad idea. Why not give us 1 refund per season? What has Riot got to lose? Here is my logic: if I have a refund, then I will be more willing to spend $ because I am in security that my buy will be good.
The other option is a testing champ/skin mode. Free rotation accomplishes some of this, but honestly, not enough. If we got a testing mode, maybe we wouldn't have made those shitty decisions we did.
