Sona's all latest unfair nerfs!(Mana cost and w nerf)

Hi guys and merry chistmas, as you see from my name i am Sona OTP and i really wanna talk about her latest nerfs [this is really big but please read it all, thank you if you gonna do it :D]. I already made a discussion about this already and i suggested to Riot to find other ways to ballance Sona. As i see some people are really happy about these nerfs, others dissagree about the bigger mana cost and her w nerf(but not the q dmg nerf)! Me personally when playing with Sona i max always her w first and as i saw after her nerf the dmg in her q did not change very much at the ability's first lvl, but while scalling the dmg is really weaker, wich makes her poke's big dmg ballanced. BUT even when maxing w, her mana bar is getting empty after some little time in the lane wich makes the nerf in her q's mana cost unballanced (not op but weaking her a lot!) cause it affects her whole kit generally, not the poke only! i understand she had to get nerfed cause of the overbearing poke dmg, that's done pretty well, but what about her mana? Come on, she is really weak at the early levels that her abillities's buffs are not really big, plus with the new nerf they cost a lot too! I tried to change my runes for Sona(focussing more in the mana regen/max mana cap) but she is still weak! I think Riot wanted to force summoners to focus more on maxing her w instead of q cause she is support, but by maxing q she was ending up being an ap damaging champion in the bot lane pretending to be supp, well that is true, this is why i am happy about the dmg nerf too, cause people may start treating her as a support now, but mana has nothing to do with the damage! I was always maxing w on her first and she was really helpfull support, but this nerf did not weaken her q's poke only, but Sona as a champion generally! I lose almost every game while playing with her and i can not find a way to fix that, even after changing runes, plus i am experienced with her and still can't do anything! Guys pls i beg you all to be objective about this discuss down in the comment section while saying your opinion, wich means you need to say the truth on what do you think about Sona's nerfs using nicely your arguments! I don't wanna see comments like: "Sona is cancer she has to be deleted, i hate her" etc. (and yeah i have seen a comment like that....jesus). So to conclude, my question is: What do you think about Sona's nerf in her q's mana cost and the nerf in the w's shield and healing, was is fair? (i say again, i dont speak about her poke damage, that was nerfed and ballanced pretty well. I speak only about her mana cost on her abillities wich is pretty high and the nerf about her w in the patch 7.22) I am really sad about Sona... She is like she got nothing good and usefull anymore, the mana nerf and the w nerfs were overdone!!! I think she is gonna be just fine if the mana cost on her q returns back to normal and her w nerf from patch 7.22 is getting recalled! Thanks for reading my discuss and i am ready to read back your opinions too, but as i said i want you all to be objective! Have a nice day summoners and i wish you all GL and HF!!! <3 :D
