Am I the only one that doesn't like the new essence system?

I really don't think that we get enough essence when we level up. Not only that but you can't reroll champ shards anymore. The amount that you can disenchant them for doesn't seem like its enough and it just makes the game seem a little less satisfying. I have 4 accounts currently (not from permabans, my first account is a little fucked up because I played ranked way before I was ready and I was just stuck in elo hell. Each account I've made has been placed higher) and I only have one that has all the champions. Its going to take forever to get all the champions on my other accounts unless I spend money to get them, which I feel is Riot's underlying intention for changing this system in the way they have.

I mean realistically, when it comes to ranked, especially in higher elo's, it can be a disadvantage if someone doesn't have all of the champions. Like you can't first or second pick high priority champs and then trade if everyone doesn't have all the champions. I feel like the game would be a lot better if they were all free and they made certain qualifications to get to play ranked (so you don't have those brand new players going into ranked playing multiple champs in the wrong roles just because). I really don't think that people spending money on buying champs would be enough to effect Riot in any major way if they changed this system either back to the way it was or altogether.

I mean all I really want is to have it be easier to get all the champions lol.
