Yeah it was hard to get the idea across in a short title, I guess I failed :(
To explain the idea:
It's so bad to have to spend 7,150 BE on getting champ level 7 by disenchanting discount champ shards. You get Blue Essence at a faster rate than IP now, but Mastery is so much more expensive now and that's what a lot of people's BE goes on... If you don't care about mastery it's cool, but if you do (because you tried hard to get the S grades) then you're quite stuck with your champion pool. The solution I suggest is a band aid at best, mastery should be cheaper in terms of BE, which is what I'm asking for in a round about way as the RP cost will always be lower than the equivalent value of BE (otherwise there's no incentive to pay with RP), and it would mean BE could be spent on champions. This change would be good for everyone imo.
If anything, this is food for thought :)
