We need an alternate path to Mastery 6-7 without blue essence

At the moment, I only have 1000 blue essence worth of champion shards. That is only enough to take two champions to 6 or one champion to 7. I have nine level 6 mastery tokens: 3 pairs and 3 singles. So unfortunately, I cannot bring 3 champions up to 6.

Yes, I know I can get random champion shards for IP, but I am saving IP for buying champions I don't own.

I propose a new system:

To get Level 6 on a champion requires one of the following: 2 Level 6 tokens and the champion permanent 2 Level 6 tokens and the champion shard 2 Level 6 tokens and 500 blue essence 4 Level 6 tokens

To get Level 6 on a champion requires one of the following: 3 Level 7 tokens and the champion permanent 3 Level 7 tokens and the champion shard 3 Level 7 tokens and 500 blue essence 4 Level 7 tokens

That way, those of us who are IP or blue essence poor can still level up our champions. It will just take a bit longer.

On an unrelated note, I think it would be a bit nicer if instead of Level 6 tokens and Level 7 tokens, it was just S-, S or S+ tokens. Then you could save your S and S+ tokens earned at level 5 for getting level 7.
