I have yet to see a Vel'koz support that doesn't feed.

I'm an ADC main, and whenever I see a Vel support on my team, I cringe.

Whenever I see him on the enemy team, I rejoice.

Yes, your poke is great. Yes, if you get an ult in a team fight from a safe distance, you can wreak havoc. Yes, you have decent CC. But that doesn't change that you're squishy as fuck and if anything sneezes at you, you die.

Maybe he's a strong pick in Diamond and above where people understand positioning and ward control, but if you don't know how to do both of those things exceptionally well, you get destroyed by anyone with a brain. Especially in the current meta, where assassins are all the rage in both mid and the jungle- it's just a bad pick.
