Analysis: Support mages, why, how, their issues and how to make them healthier.
Hi, i'd like to talk about SUPPORT MAGES, why do they work, how do they work and how to improve their gameplay and make it better for them, their allies and enemies.
Which champions are mage supports?
Most popular/most mages used as supports:
Mages used as supports in past/less popular mage supports:

Notice this:
- All 8 of them are** IMMOBILE**
- They all have really good ZONE CONTROL and/or threat zones
- 7 of them have at least 1 HARD CC ability, the last one, Lux, has ROOT
- 6 of them are heavily SKILLSHOT based champions
- Their abilities are weak on their own, but strong when combined (COMBOs)
Why are mages migrating to support role?
This is speculation, and im open to discussion, but this is what i think: There's way too much MOBILITY and CDR in** MID LANE** and JUNGLE. Because these champions lack mobility, they can't really escape from all these dashes and blinks, especially when such abilities come from both enemy mid and jungle. This means they have harder time to survive ganks/deny aggression.
Very high mobility (coming from both MS and dashes) makes their skillshot/combo based kits very UNRELIABLE. Sure they can work, but it's really hard to hit Zed/Yasuo/LV with telegraphed abilities. While CDR is much more acessible to these mages, they are still gated by mana so they can't just mindlessly spam abilities and hope something sticks.
If there's place where this mobility creep isn't as prevalent its BOT LANE. ADCs have average mobility and traditional supports have next to none. This makes their abilities easier to land and they are much less likely to be jumped at.
How come mages (designed to be high-income champions) work in support role (low-income)?
They don't. If you took any mage and gave him support's income, he would be just bad. But, there comes the ADC. ADC is what makes support mages viable. Let me explain.
ADCs have weak-ish early and mid game, they offer steady DPS at average range. Mages have okay-ish early, strong mid and late, damage downtimes and strong zone control.
If solo lane mage messes up his combo, he's very vulnerable as he can't retaliate against attacks. If he lands his combo, he won the trade and probably got the kill. Presence of ADC allows him to fall back and wait on his CDs, so he can try again, plus the mage doesn't have to worry about getting CS/wave control. Presence of ADC also allows mage to focus FULLY ON DAMAGE. So while he has decreased income, he can still get similar levels of damage because he doesn't have to spend gold on defensive items. There's a reason support mages almost never build Zhonya's or Abyssal until 5th-6th item. ADC also offers limited CC, which allows mage to land his abilities even more reliably. This is especially true for Ashe, Jhin and Varus.
What does ADC gain? Two important things ADCs lack: Zone control and threat. For example, when you are playing Ashe and you're supported by Janna, there isn't much threat for Draven so he can just throw his Qs at you anytime he wants. Janna can't really do much, just shield you and that's it. But when you are playing Ashe and you're supported by Brand, this Draven will think twice before doing such trades as aggression like this will most likely end up in pillar below his feet and thus unfavourable trade.
Sure, ADCs aren't as strong with mage support as they are with traditional peel/protect support, but sum of ADC+MAGE impact is greater than that of ADC+Support's.
What are issues of these MAGE SUPPORTS?
-Frontloaded damage. This is large issue on Brand and Zyra in particular. In Brand's case, it's maxing W and doing way too much up-front damage with it. In Zyra's case, it's Q on passive which also instantly procs thunderlords and results in low-risk/high-reward situations. These champions shouldn't be able to do much damage up front, but to build their damage into obscene levels as the encounter prolongs.
-Late-game identity/role. Not much of an issue, but look at it this way: in late-game everyone wants to kill enemy team. There's very little difference between actual mid champion and mage support
How to improve these support mages and make them more fair?
Move their up-front damage into delayed/conditional damage. For example:
-Lower QWE damage by ~50% (both bases and scaling)
-Passive burn always does damage to minions/monsters as if it had 3 stacks
-Passive burn AP ratio increased from 0.015 to 0.03
-Applying passive to targets that are about to explode (2 sec window after third stack) increases explosion damage by 50%, not prolonging the countdown.
This makes him much more manageable in lane, however if he manages to get his combo off on multiple targets (play as he is designed to) he gets greatly rewarded by fireworks with insane damage. As bulk of his damage comes from explosion, he will always try to land as many abilities as possible instead of using his abilities in fire-and-forget fashion.
