Hey this is a post about Support Velkoz (And Actually Building Support)
If you wanna TLDR the Final Build looks like so

Now let me just, stop you before you say "This wont work in high elos" which, no shit it wouldn't. There are plenty of other utility supports that provide utility far better, so this would be redundant past /maybe/ gold. Really though where this shines is the fact that while still providing a decent amount of damage mitigation and utility to your team, you are also dishing out around 2.5k Damage with your full combo.
I've noticed that a lot of off meta supports that strive well in low elos build full damage, and I feel that building full damage eventually becomes redundant. If you have 5 people building full damage against 5 people building full damage, really its just a waiting game for who makes the first move.
However if you build utility, you lower the enemy teams damage by mitigating or reversing it, and simultaneously increase the damage your team does by 1) Keep them alive and B) increasing their attack speed via Ardent.
Now there aren't a lot of mages that could build full utility and still be relevent in regards to damage simply because a lot of them rely so heavily on scaling. The only one that I can't think of relying super heavy on scaling is Brand, due to his % health. The reason I suggest Velkoz is simply due to his true damage passive.
Vel koz's scalings are actually not really that good. Of course a full AP Vel Koz will out damage a Utility Koz, but really, that's just obvious. But with building utility on velkoz you can still stand strong in the ring of damage while doing what you can to help your laner, and the rest of the team survive during hectic situations.
Sure you can keep people alive as Lulu, Janna, Nami and such, but if you're low elo you also have to take into account that in general, EVERYONE'S positioning is signifcantly worse than other ELOs, which means more opportunities to land core skill shot. Vel Koz thrives in an area where people don't know where to stand.
Trick question don't stand anywere keep moving.
But I digress. Is Vel Koz Support a secret OP? No.
Is Vel Koz Support Viable? Conditionally
Is Vel Koz Support a good Sleeper Pick for someone who has a grasp on the mechanics of his kit? Hell fucking yes.
If yall give me some time I can get you the actual numbers on his damage out put and his stats in a bit.
