Blind Pick Mode where you can ACTUALLY learn new Champions
Most of the people who want to learn new Champions play of course Normal Games. Either Draft, buts mostly Blind Pick. They often face the problem (especially in Top and Mid lane) that they have to face people who play their Main in a Normal Game for whatever reason. This just happened to me, when trying to learn Kled, but I couldn't learn much, because I was in Grey Screen most of the time. So how about another Blind Pick Mode, where you can only play Champions, you don't have on Level 6+. The reason why Champion Mastery 6 and not earlier, is because there are some difficult champions, you need way more games to learn the basics, than it takes to get them to Champ Mastery 6.
Just an idea tho.
