Mana Regen: (Of champions under support category)
Sona: 7.0 + 0.65
Orianna 7.0 + 0.5
Janna: 6.9 + 0.6
Morgana: 6.8 + 0.68
Lux: 5.0 + 0.6 (Who's already received many complaints about her mana regen)
Soraka: 4.3 + 0.45

I think this was set that low because Soraka could replenish her own mana with infuse. Now that she can not, I think it's important for her to get a major buff to her mana regen, especially when her spells scale to a higher mana cost late game. I think Riot missed this detail when nerfing her.

P.S Note to Riot
Please stop nerfing the few viable supports and start buffing the other ones. =(

at first i was like everyone else and went pffft phil stone is all we need but actually playing her i dont feel like soraka anymore. even the times i get a morellos and a phil stone ive still oomed in drawn out poke wars. or even when we are just pushing a lane with minor skirmishes.

i dont think a mana regn buff would be such a game changing deal to give her. soraka will still oom from using heal on cd but it will help later on in the game when you shouldnt be having the mana issues mages are having. i mean what other support ooms that fast? even sona doesnt oom as fast as soraka does without the infuse. shes still built around like she has it. if you are going to nerf her fix her stats plz.

worst part is they said multiple times soraka is fine. and sonas auras wouldnt be touched but you lied to us. i agree with the op. the only reason soraka and sona were used is because the other supports are less attractive choices. buff the others not nerf the good ones. its like common sense... a few alistar changes like last patch isnt suddenly going to make him used more than sona soraka. the only reason you might see more of him if any is due to the sona nerfs.

we shouldnt have to go mana regn runes or masteries to compensate for poor base mana regn. we should be going them if we want to play a more spammy playstyle. thats the entire reason the new masteries give us choices. im not saying its a must for new soraka but the more im experimenting with her new auto attack and armor pent etc, the more i realize just how limited the infuse change makes varied soraka builds.

This actually makes sense.

Bump for very sensible issue.

I wouldn't be surprised if Soraka's mana regen was also removed from the game at this rate.

/sarcasm

Much butthurt, in this support nerf. (Personally, I like playing "unconventional" supports. Blitzcrank, Karthus, Ashe.)

That being said, I do agree with the OP. Her mana re-gen is sooooooo low right now.

I bump thee

Word. Wouldn't make her broken. As it stands now, 4 heals and she's out of mana. The one really good thing about Soraka before was that you could get more wards and an early HoG since you didn't have to itemize/rune/mastery for mana. She doesn't scale into late game quite as well as other supports since she doesn't have hard cc, and the thing that kept her from being killed in lane (since she has no way to protect herself other than a silence) was that early health item.

Here's a little suggestion:
I think Riot was trying to not let her have infinite resources in holding a lane, especially when she's alone (As supports are supposed to be partner dependent). Perhaps instead of removing her self infuse completely, we make it that she can only use it on enemies or teammates but gets half of that mana restored to herself when used on a teammate?
