I used to be elite-tier at Halo, and honestly the noobs killed me more than people at my level.

At a certain skill level the game changes from “who’s clicking who first” to “who’s controlling the best space/resource/angle”, which becomes “how can I best deny my opponent that angle” which becomes “how can I outmaneouvre the opponent while they try to deny my obvious attempt to deny them the space”.

None of the above enters a noobs head. Which is how I get surprised to death by a kid on his 3rd game.
