Why can't we modify rune pages in champion selection?
I understand the desire to make money by selling more rune pages but this is a huge inconvenience. For instance, MR glyphs would be useless in mid lane against an AD assassin, so one has to create 2 rune pages before the matchup is known to cover the likely scenarios for 1 type of champion and role.
There are better ways to monetize. Limiting rune page accessibility for even those who pay for them is a negative part of the game.
