Riot's treatment of Mage Runes

Love it. Take away 2 keystones, give them to enchanters (Aery) and Bruisers/Assassins (Phase Rush). Then nerf Celerity because of ADCs. Then nerf Gathering Storm because of ADCs. Gut manaflow band. Then take away Ultimate Hat and give THAT to assassins/bruisers as well IN TWO WAYS (Literally past Ultimate Hat onto Domination tree, while also replacing Ulti Hat in Sorcery with Nimbus Cloak which is useless for the vast majority of mage.
Now on PBE they're making minion dematerializer give you attack speed when used on cannon minions instead of % damage to structures. (Which was actually great.)
I'm beginning to feel extremely disenfranchised by Riot's balance team. As if they haven't got a single mage player.
