TF2 isn’t designed to be as competitive as deadlock. It’s a goofy game that’s mostly just designed for fun. (Competitive TF2 does exist and I am a fan of it but it’s not really officially supported in any meaningful way.)

Deadlock on the other hand is designed to be a very competitive MOBA where individual decisions will greatly change a games outcomes. I would look at DOTA as a better comparison than TF2.
