Chief being average is what makes him the best. Because it means that unlike specialists, there's nothing he can't do well. He's versatile.
Also, the reason they say he's average as opposed to giving him a designated role is so that you can do anything in the games. Its the same reason why the Rookie and Noble 6 didn't have designed roles on their respective teams, despite everybody else obviously having a specialty.
Chief / Noble 6 / the Rookie's specialty is your specialty. If you're best at sniping, then Chief is a sniper. If you're good at driving, then Chief is a vehicles specialist. Etc.
I don't believe in luck. So your saying he's the most skilled?
No i'm saying he's the luckiest, even the games say this...
He's actually one of the worst Spartans, just EXTREMELY lucky.
What? He isn't the worst, but he's not the best. He's slightly above average.
I highly doubt Kelly or Fred and that other chick could do what John did the past 4 games.
They could have, just with utilizing different methods. This is of course going on the theory that they also had Cortana with them. Kelly is the fastest, Linda is the best marksman, and Fred is essentially just like the Chief.
Yeah, and the whole concept is bull**** because "luck" is not a quality.
I hate when people act as though luck is a tangible thing you can have at all times, and like Chief is never unlucky.
Here's a thought guys; Chief gets caught up in the most unlucky situations int he war. At the end of Halo 3, the Arbiter makes it back to Earth but Chief was UNLUCKY enough to get stuck in the part of the Dawn that didn't make the jump. At the beginning of Halo 4, Chief is UNLUCKY enough to be stumbled upon not by the UNSC, or even a friendly covenant ally, but by literally the only space faring faction who would have attacked him.
That's what you think luck is? Being continuously in the wrong place at the wrong time, and having to fight your way out of the worst situations of anybody involved?
Halsey says he's lucky, but all evidence points to her being wrong.
