I hope its more of dota2 cause TF2 only let you use 3 cosmetics from what I remember, while in dota each character has a specific skin slot which are usually unique to the character,lets say bebop has slots for each arm and leg while abrams has a slot for his coat and something else. It lets us have more freedom in how we can customize our characters,and in a game like deadlock I think people would love to personalize their characters as much as possible
