its the fact that they are jerk nerfing some champs now before removing it , while mages are already struggling with mana nerfs agasinst the new assassin/energy/resourcless meta , they also up the morello cost, chalice STILL is THE worse alternative out of all mana regen items
also , itemization for mages sucks
asassins can go straight into their core dmg builds since their first B , mana users like syndra wich got further nerfed, HAVE to waste their first item slot on mana regen JUST to be able to stay in lane , the SECOND you move from mid , zed or kat, or any of the other spammed mids right now will utterly murder your tower before you get back , so being without regen first is NOT an option even then, you are behind in terms of building your core compared to said assasins that for the most part, have better early wave clear than you do wich shouldn't be but it is..
as it stands there is no mage mana regen item that gives you ap and mana regen from the start its either one or the other we don't get that benefit like energy users do
right now, the only one im having some success with is velkoz on account he does true dmg and doesn't need much ap to hit hard so rushing mana regen on him doesn't put him as behind comparatively as other ap casters or nukers
I agree though, most champs don't "need it" I think the exception is ahri because she did got nerfed because of the existence of this item, most other mages adapted it at some point for overkill potential but I think the few that might need it and miss it are ahri and syndra, maaaybe leblanc but she will still do good without it
