[2019] Zyra ult cost changed to 100 mana at all levels, 3-4 champs left to go

Amumu 100/150/200
Vi 100/125/150
Zilean 125/150/175
And the odd one Twisted Fate 150/125/100

These are mostly because of an old balancing way left from season 2-4 (beside TF who probably has that to mana gate him early on), after that the champions released had a constant 100 mana cost (keep in mind that I do not count toggles/low CD ults like Anivia, Corki, Zoe or stacking ults like Kassadin and Kog'Maw, their cost isn't 100 for a different reason), while slowly bringing in line other champs either through reworks or direct mana costs like Zyra or Karthus last year.

Note: There's also Sylas who has 75 mana cost at all ranks and while they probably did this to make up for all the different costs of ults he can steal, I wouldn't mind Riot rising his cost to 100 :^ ).

Also I want to be clear that these changes are for the sake of consistency, not because I think one of those champs needs buffs and that this is the change they need or something like that. So please keep comments about weather X champ is already strong or that these are not gonna bring X champ back in the meta etc. out of disscusion, this is not the point of this post. If a champ on the list is too strong to get any buffs, then simply wait till next rounds of nerfs to also bring them in line.

League boards mirror post. Maybe they will notice this way.
