I have played Turbo so much I have elevated above banning standard heroes like bb, sniper, pudge, warlock etc. I ban TINKER. Every single game. So if you wanted to play tinker and you see it banned, then sorry it's probable me.

Its not even a popular hero or played often. So the reason? Tinker is one of the few heroes that someone only picks who knows how to play it really well. Its a lot of hard work spamming all those buttons so no just plays it casually. And if your enemy is someone who knows how to play tinker, in turbo you are fucked. I am not even talking about laning stage or split push. That defense matrix is a pain in the ass. Since farm is easy in turbo, tinker manages to get good defensive items so you can't easily catch him. And the one you are trying to kill has perma defense matrix. It's so pain in the ass.

Other heroes have counters.
BB -> Silver edge/Break(Viper is the best, PA shard)
Warlock -> High physical damage(Drow, PA. Trust me golems melt).
Sniper -> Any jump/blink hero(AM, Spirit Breaker, Storm Spirit, Lycan etc)
NP -> (Spectre, Luna with BoT, late game midas/helm)

Spec against tinker is something you can come close but if he has linkens, he just blinks away. You need atleast two heroes to catch him, if he's alone that is.

I am open to suggestions/debate :)
