Hello! I am Tourizm a long time League of Legends Player since season 3! Since Season 5 I have almost just played Support in all different variations, styles, and Champions.
I have peaked in Diamond 4 last season, were I maintain until today. Since Soraka came out her Kit, Playstyle and Champion design hooked me. Until today I play her regularly and overall I've played over 500 Soraka Games in Gold-Diamond Elo.
I attend to stream regularly and if you want I would highly appreciate it, if you check out my Twitch Channel. Here Is my Channel

Pros

+ Very Strong Peel + Massive Healing + She is fast when Saving Low Teammates + Global Heal Ultimate + Alot of Sustain for Teammates + Throws Bananas

Cons

- Squishy - Needs very Well Makro Knowledge eg when to commit and when not - Hitting your Q is essential - Positioning is very important - Sacrifing her Health - High Cooldowns at the Start

She is a more subtle ****-blocker than Janna. She is a healer but she also provides a great amount of utility with items (duh) and her kit if you know how to use it well and position perfectly.

In lane

: you NEED to play aggressively, to do this varies in difficulty depending on who you are versing. The reason you need to play aggro and harass the enemy duo is that Soraka is incredibly vulnerable to ganks since she is squishy, immobile, and has no reliable CC. Soraka wins trades because of her sustain with spammable Q + AA trades.

Against Zyra/Brand, they have high base damage so if you can bait out their main damage ability then go balls to the wall while it's on CD you will at least go even if not win lane. Just don't feed them early kills and you will outscale. Early boots against Brand are very useful to dodge his W

Against tanks/engage supports: you have to harass them level 1 so they can't all-in you level 2 (since most of them hit their first spike at lvl 2 - think Ali combo, Leona EQ etc). Then they will be to low to all in you. Then you need to keep abusing your range and strong of trades with AA+Q when their engage tool in on cd so a) they are too weak to engage b) it makes jungle ganks looks less appealing to the enemy jungle because, again, if you get ganked or dove and you are in a position where you can't just run away, you will die.[/b][/b][/b]

Against enchanters: you basically just have to not be a *****. Don't be scared of their damage, just eat it and Q+AA spam and you will win trades. Use your Q passive (bonus MS when running away from enemies) to kite like a boss.

Team fights: this is where positioning matters a lot. You want to use your heal on your front line since HP is "worth more" on them because they have resistances. So you need to position kind of in between frontline and your carries. Your heal is spammable, which is nice, but it costs 10% max HP per cast so you might also need to try hit some Q's or you'll just be sitting around low HP. Your Q passive is great for this because it helps you run up, land a Q, and speed away.
Keep an eye on your teammates in lane once you have 6 and LET THEM KNOW you have ult so they can either commit to a dive knowing you've got their back, or that they can bait the enemy in to overcommitting to a fight. Make sure you frequently scan your camera to look at your teammates so you don't waste your ulti. I've wasted mine a few times on e.g. Illaoi/Nasus who were fine to 1v2 without my help. Or I've stupidly used it on an ally Tryndamere and Zilean lul.
