I can see the "You're better, let me show you my tactics" point, although with my patience and lack of interests when it comes to competetive mp games i really really do not feel like it's worth it.

But when I'm the one who stomp the shit out of people, well, I do have the time of my life.

Singleplayer games, more my thing.
Or just coop.

Precisely!
When playing fair gets you killed being a sneaky, conniving, backstabbing asshole to the guy is always the way to go (for me, anyway). And it's fun too.
Tactics! :P
