Hextech Crafting punishing long time players.

So today i found out that the system (hextech crafting) is rigid for people who have played the game for so long and have finally acquired all the champions in the game to lose out and and lose money on this system. I want to know what is the point of spending money and when riot just keeps giving champions shards and champion permanence if people own all the champions for example: I got 3 champion shards and re-rolled it thinking your team would have the decency to give us a skin instead or something instead now I have an Orianna permanent unlocked but sitting there like a skin but with nothing of use. Not only that but it can't only disenchant into blue essence. So tell me riot what am i suppose to do here cause i spent money for 3 boxes to get ripped off by your system. We can't do anything but deal with it instead of getting a skin or refund? Like I rather spend money on a skin than have a champion permanence. Can't you fix your system. Like i don't get your system if one has dedicated themselves in this game for so long. Like i love playing his game and i have always had fun with it with my friends. Yet i get ripped off by this nonsense... I don't understand... Riot you are punishing players that have played and loved to have fun in this game to the point where they have gotten everyone and in return give them... give them nothing. I am not even mad but if i spent money on this game i want it to be used for good like skins or fun hextech unboxing skin shards. Not things i own. So Riot I believe that there needs to be a way for people who own all the champs not to be punished in this system. I understand it is all coded but I feel this is unjustified.
