Unlockable content

It would be really nice if...whenever we hit, let's say 100k mastery points with a certain champion we could unlock a icon for that champion. Also, we all know how hard it is to get ip for new rune pages/runes in general or new champions that we wanna try, and we don't all have enough time to make that ip as fastest as we expect to do and for every champion of ours that hit lvl 5 mastery we should be rewarded, with...1000 IP for example.
