A gripe with the refund system

As someone who has spent and embarrassing amount (>$500)on this game, I am bound to make a few purchases I regret, and thankfully, there is a refund system that exists, but the static 3 refund amount no exception bothers me. There should be a way to earn more refund tokens, or an adjustment to the way they work.

As for earning more, it would be a nice way to reward players who have contributed a lot of money to the further development of the game(and the development of some individual's pockets) that doesn't show how much a player has spent. What I mean by this is one incentive for regular spending is the hextech skins, but personally when I see them I feel a bit less jealous and think more about how much cost went into them. Refunds happen in the background and player's wouldn't be openly displaying how much the player has thrown at the game. And it would always be nice to have some sort of reward for spending so much, as not m(any) of those exist at the moment that I am aware of.

As for adjustments, a refund token being used on an $20 skin and a 450 blue essence champ and both using the same token for it feels kinda weird.
