These new rune changes suck and instead of bringing Diversity, it just pushes players to do the same

Serious how many mid laners do you see spamming Summon Aery? Only in the rare cases would a mid take arcane comet (Xerath) Just tell me how is this Diverse at all? And dont even get me started on manaflow band... basically take this rune to mindlessly spam spells and win lane... Like who balances this stuff? is it all done in America?
