Eternals and champion cost

The high cost of champions has always been something that bothers me a little but not enough to post about it, until now. With the upcoming release of eternals and them also costing blue essence that makes it super hard to continue getting all the champions.

The Problem: Buying one champion has always felt fair enough. If you really want to try out X champion you save up a bit and get it. The big problem comes when trying to get champions that you don't really want. I'm a support one trick and I've played and enjoyed all the supports, but as someone who has friends it's really annoying when they ask me to lock someone in for them but I can't. I've been playing this game for just over two years now and despite getting 200+ champion capsules and only buying champions with shards, I'm still only about half way to unlocking all the champions. If I start buying Eternals for my favorite champions that only adds years onto how long it will be before I can star locking in for all my friends.

Possible Solutions: One great solution would be adding some kind of method to bypass the problem all together. A possible and simple way to do this would be a way to offer to trade pick order positions with someone. Of course this would result in everyone spamming up to trade with last pick but this might be fixable by making it where you can only offer to trade with people above you in the order (and then people would just ask in chat if they want to trade lower). Another solution would be making it where the champions are cheaper in some way. This could be done in a few ways. The simplest would be just reducing all of their costs. Another would be reducing their prices further sooner but keeping new releases where they are. Or maybe make it where champion prices are reduced based on how many champions you've already bought.
