 We're just saying that tanks are inferior arena combatants, because they are limited to driving around and shooting at stuff, whereas every-single-character-in-the-history-of-ever have a multitude of different ways to approach and decimate their enemies.

You're assuming one futuristic armored vehicle can't come equipped with a multitude of supplementary abilities to add more variation to its own combat style.

Just seeing if I understood the first part of that correctly; So, if the humanoid tank man walks headfirst towards the tank, he dies. Which inadvertadly means that if the tank drives headfirst towards humanoid tank man, it dies, because they're the same, except one of them has superior movement capabilities, and can jump, duck, and even punch.Arena fights are based around two people meeting each other headfirst in a clash of skill and power. Humanoid tank man and the tank would instantly kill eachother, unless human tank man ducked.Also, no one is saying that single characters are 1-hit wonders against tanks.[/quote]

A sane tanker wouldn't drive heard-first into a risky situation unless it was absolutely needed. Somewhat related, but I wouldn't be surprised if tank crews felt a little invulnerable in their war machines, but I bet seasoned tank crews and [b]not[/b] greenhorns know full-well that an MBT is far from invincible. In truth, if I had a character like this, I'd just hit the reverse while blasting away at your character until I won the fight (which falls into the Boring, But Practical Trope---which conflicts with the Rule of Cool trope of which I adore immensely). 

Also, I don't see why you can't have a clash of skill and power using sophisticated technology like armored vehicles and whatnot. To me, this looks like an opinion or personal preference of a lone individual (or a small niche group of roleplayers of like-minded interest) trying to be passed off as the norm, the rule and an expectation, honestly.

Also tanks are slow at turning.
