Mastery Changes in PBE: Screwing over mana mages in early game?

Meditation will now only be available as a tier 4 mastery in support, and though it's a lot stronger there working like a Chalice of Harmony, it means that mana mages like Lux, Syndra, Ziggs, etc., no longer have that +3 per 5 mana regen early-game. That is kinda debilitating, and having 75 extra maximum mana at level 1 isn't gonna help much.

Oh, one extra spell instead of barely sustainable mana early on? How am I supposed to counter Zed by harassing him early if I can't fire more than 3 spells before a burnout? And no, Doran's Ring can't do it all, especially if you get zoned; once you're zoned, you can't counterzone because you'll manaburn!

And I thought you guys were gonna let Lux have some love with her new skin. Now you're just making her early game even worse against the meta manaless mids (Zed, Kat, etc.).

Riot, I hope these changes are also going to include some early buffs for mana mages, or they are going to get CROWDED OUT!
