There's a logical gap in how the mana changes are being applied

My biggest issue with the mana changes was that every mid laner was nerfed almost equally, regardless of which function they're supposed to fulfill as a character, or their current place in the meta.

For example:

Level 1 Mana Regen :: 1.2 per second >>> 1.6 per second Level 1 Mana Pool :: 334 >>> 418 Mana Per Level :: 50 >>> 25

• Level 1 Mana Regen :: 1.2 per second >>> 1.6 per second
• Level 1 Mana Pool :: 396 >>> 495 ** Mana Per Level :: 50 >>> 25

Ahri is a mage-assassin, while Anivia is a control-oriented mage. Their changes are almost identical, even though Anivia has long been known as a wave-pusher while Ahri is more pick-oriented. The problem is that in the scenario where each manage their mana somewhat equally, Anivia will not be able to fulfill her intended wave-pushing purpose whereas Ahri will still be a solid assassin in the mid-to-late game.

having his mana growth shaved in half when he depends on his Q to farm, already builds mana items and routinely mana-starved himself already is so insane to me that it borders on me thinking Riot actually hates that champion. This isn't even about him casting spells willy-nilly; it will completely neuter his ability to farm without taking teleport to replenish at turret.

is already a champion that sees an extremely low amount of play due to how crazy her mana costs are, and they're now going to become worse. I know she has a small buff coming to her Q on the PBE, but the blanket nerf applied to her along with every other mages will impact her a lot more.

ooms herself after casting a couple E's since it costs more than her ultimate, and she isn't contested specifically because of the fact that she's not able to push waves like the other meta mid laners yet she's taking a hit. Edit: There are now additional Lux changes on the PBE aimed at reducing her mana costs and help with her passive procs, which should help her waveclear somewhat and bring her more in line with other artillery mages.

didn't get a change even though he only needs to throw Q to clear a wave. Somehow, he has an insane amount of wave pushing potential even though he's an assassin and gets to maintain it while every mage is getting this aspect of their kit nerfed.

will now have such low amount of mana that he will simply never be able to shove a lane in order to gank without significantly investing into mana items, completely making his intended role as a ganking mage irrelevant (not that it wasn't already due to Taliyah having taken over that spot from him ages ago).

Some characters absolutely needed the nerf due to their ability to permashove a wave after level 9, but other cases like mentioned above don't make any sense to me. It's like Riot looked at Taliyah, Ryze and Cass' wave pushing and then nerfed everyone due to these champion's ability to shove waves while scaling incredibly hard into the late game, rather than evaluating the issue on a case-by-case basis. I'd like to get some input from a Rioter in this because I fail to see how fucking also got hit by these changes.
