Not damage wise, I think that one part is fine, but the Mana-Costs and the Cooldown seem to be extremly high - something I cannot really understand, as the skill itself might sound strong on paper, but some enemies can literally walk through the zone and manage to get out without the second part of it activating.
Also I think she could use some small buffs (but not on her healing powers, those are already op).
SaltyToplaneGoat3 votesHmmm, on another note: how about adding a weak slow to the silence? Nothing big, just 10% or so... just to prevent people from walking right through it...
Duke Anax2 votesThey are supposed to walk through. Most of the time you use either the first or the second part of the spell, rarely both.
If the root were almost guaranteed after the silence the spell would be too strong, but if you wanna add a slow you can buy Rylais.
MisterHealYoGirl2 votesIt actually says in the spotlight that it was calculated so that any champion in the game could walk across the entire thing without boots. You can slow them with your Q, though, or follow up on allied crowd control. (Amumu/Soraka is brutal.)
Aeolian Melodies3 votesMana costs and CDs are fine imo.
I'm also fine with the delay for the snare.
I just want the silence to proc when it says it does.
I don't play her but I got her in an aram lately, Amumu Q's my ally, I lay E on his feet as soon as he arrives because I know the ult is coming.
Mumu sits on the zone and ults anyway.
fml.
Duke Anax1 votesActually I think her healing could use a bit of help in certain situations. She brings a lot of sustain, but in combat, especially in clutch situations it is really difficult to keep teammates alive.
What I would like to see is Equinox heal for equal amounts as damage. And only if it does damage. That way it can'tr be used for sustain but gives another clutch heal. That also enforces tghe abbiliy identity as an anti assassin tool.
CasterGilgamesh1 votesi would like it if they just removed the mana cost on her heal since she already pays 10% of her max health for it

No because she heals herself back with Q - she'd have to be tuned to mathematically ALWAYS pay more than she can regain for it to be balanced without a mana cost.

Why? If she still had to hit enemy champions to regain health, it seems balanced to me. Hit an ability, be able to heal for 240+ health or so by sacrificing the health gained.
CasterGilgamesh1 voteslol what? she loses 10% of her max health and uses mana for every other spell. her ult cd is not short enough to make use of it during laning phase to stay in lane. her q is easy to dodge without even boots same with her silence you need to max her heal first since you are mostly using its base heal early game until you get a decent enough ap to augment it with .not to mention that she lacks reliable hard cc unlike supports like 
.and what's funny is even though she could out sustain them they can engaged so well even when she has her silence field.not to mention that and have a heal in their kit.Of course soraka out heals them but they can just cc her adc and she can't do a thing they can set up ganks very well on top of that.
Feathermane1 votesHer W is so powerful, the rest of her kit has to be crap to compensate. Definitely against buffs unless heals are nerfed alongside them.
SaltyToplaneGoat2 votesShe's dealing true % max health damage to herself in order to use it... PLUS mana costs... I think that balances it out again...
Krinu1 votesBuy a 
. It goes from "a joke" to "really scary" super fast.
lostbob1171 votesI think it'd be cool to buff her E, but I think the W heal should be changed for over time healing instead of instant healing.
Zone of Endless1 votesher E is one of the strongest CC in the game. There's no reason to buff anymore.
An AoE silence you can just plop down and no counterplay behind that. It can easily turn a teamfight because she just put it under the ADC/any carries getting focused, and the tank/assassin can only AA him instead of killing the carry or CC the carry.
