The Champion Mastery Level 7 Challenge!

Ok, so Champion Mastery Level 6 and 7 are out. This thread isn't to discuss if its good or not, just a way to make it fun.

For the sack of this idea I won't be talking about the Champion Essence combine costs.

For those who don't know you need to get an S-, S, or S+ twice in order to get Level 6, and then for level 7 you need to get an S, or S+ three times.

For a total of 5 tokens.

So what my idea is, is that you need to get one token from each role. ADC, Support, Middle, Top, and Jungle. This way you can "show" true mastery of a champion. Obviously this will be easier on some champions than others, but I was just wondering what you all thought of this idea, obviously it would be self-imposed.
