clyph0rdwhy play dm instead of just pugging 6s if you want good aim
oh yeah because intentional practice allows you to improve weaker areas or prerequisite skills at a faster rate than just going for something beyond your ability right off the bat
because dm is nonstop dm practice opposed to pugs which have tons of dead time
and if a dm server is "beyond your ability" I dont think playing some random aim training game is gonna help you, especially considering how tf2 is much more then just aiming, for example map knowledge and movement skills. This game isn't gonna teach you where the ammo packs are or how to air strafe and rocket jump.
just play tf2 if you want to get better at tf2
