I have a suggestion regarding level up loot, opinions and possible or not?

Hey, So one of my accounts is over the 175 mark of levels now, and i have been thinking, what do i have to look forward to when i level each time? A champion capsule? Well i cant really look forward to it seeing as i already own every champion, sure i can get more blue essence from disenchanting the champion shards, but it seems like a wasted opportunity, i think that once you have all the champions, it should start to give skin fragments, or maybe even trial ONLY skin shards? I think it would be better that way only because of the fact that i have no need for the champion shards, or much use for the blue essence, sure i could wait for the blue essence emporium again, but it doesn't really have much in the way of stuff i want. I WOULD say something along the lines of like 100 rp per level, but that seems like it could end up breaking the economy with people making smurfs. so i dont actually suggest that. unless you guys already have ideas about level rewards that we arent aware of, i just feel like the current ones fall short.
