BE Definitely should not cost so much for champion mastery

Before the conversion to BE it was all fine and dandy that champion mastery required BE to do because there wasn't really anything else to spend it on. Now that BE is an integral part of the system for purchasing things in League I feel that still requiring us to use BE to unlock champion mastery is unnecessary and the fact that the price was even raised after the conversion is frustrating. Considering players (especially newer ones) have to grind out a lot of games to get enough BE to even buy champions I think it's unfair that you have to also use a ton of BE to get champion mastery for a champion you like. It should at least go back to the initial price it was at because the current price is just straight up unfair no matter how much BE you can get for leveling up.
