Annie and Brand and why they aren't supports
Alright, before I get hated completely for saying this, I want you guys to open your champion slot before game and look through all champions there are a total of 25 champions that could do the support role, yet people would rather play as Annie, or Brand which are not supports they are mages.

Even some tanks could be valuable supports like Shen, Wukong, Blitzcrank just to name a few for there different reasons with the addition of them being tanky. What does Annie and Brand have:
Annie-Passive after 4 spells she can cast any spell and it stuns her target, most commonly used in conjunction with her AOE sometimes single target and most commonly her ult. Brand-Passive after hitting a target with a spell he can then stun them with his q. Noticed how these two champions only support ability is situation and relies on something else having to happen first given it's easy to get the ability to use these stuns, it doesn't make them support just because you have 1 cc effect doesn't qualify you as a sup. Xin Xhao, Yasuo Malzahar, Gangplank just to name a few all have cc effects some like Gangplank has 2 of them, but they are not supports neither are Annie and Brand. People say well they do well down at bot, well duh, they are mages, mages counter the f out of adcs and the typical supports were nerfed to hell so they couldn't dish out as much damage giving any lane with Annie and Brand a huge advantage and could easily zone out their counter parts. You have 25 options for supports use them master them you'll find that they all are viable in your own ways, they might not do as much damage as an Annie or Brand but that's because they aren't meant to. Just like with Ashe as an adc she doesn't counter anyone because of her damage it's because of her utility that makes her viable and can win her her lane easily same with supports. What makes a champion a support is not their cc effect it's their kit and how it's designed most of these champions above have several cc effects/buffs/shields/steroids/heals that's why they're supports. I don't want to hear any arguments to support why you guys feel that Annie and Brand are supports I've already heard them all but even Riot stated that they're not supports they weren't built to be supports so stop using them in that way or eventually riot is going to nerf them so hard they won't even be viable in their actual positions anymore.

are out of the picture even though their spells are extremely good for support.
are strong mage supports: they have low mana costs, high base damage/CC and don't need alot of money.
