I don't understand why this game has a class system AND a weight system. I also don't get limiting skills to a class, and one class to each character.
The TTK and game flow is too fast to be thinking "Oh, he looks like an Infiltrator, let me vary my tactics to..." no. The classes don't play differently enough for that to matter anyway, there's just arbitrary constraints on what certain classes can do.
Also I dislike stealth camo outside of Cloak and Dagger. People don't use it to hide as much as they use it to confuse you for a second as they sprint towards you for a CQC grab. Something like Peace Walker's stealth mat, that functions like Octocamo, feels like it would encourage genuine stealth more.
