The mana regen "nerfs" explained with Math!
Let's say we have a level 6
with a and 793.52 mana and 11.4 base mana regeneration
11.4 mana/5sec
793.52 max mana
Old mana font: 27.6 mana/5sec
New mana font: 25.04 mana/5sec
Now lets say that she is now level 11! Her base current stats are:
13 mana/5sec
1113.52 max mana
+
Old mana font: 30 mana/5sec
New mana font: 30.6 mana/5sec
First of all, why Janna? Because she has the most mana at level 18. Okay, but I heard that mana regen was nerfed, like a lot! It was in the early game. ...Then what was the point of this? I'll explain in another formula!
+
... for some reason(+500 max mana for simplicities sake)
Old mana font: 39 mana/5sec
New mana font: 42 mana/5sec
What I'm basically trying to say is that many people do not feel that mana regen buff because Chailice now scales with max mana instead of mana regen and nobody is used to buying mana itself for mana regen.
If I made any mistakes in my math please let me know!
