So because there are plans for a few new unlocks...people start assuming TF2's becoming a RPG? Nice leap in logic. No need to look at this rationally, lets just make stupid assumptions about what TF2 will be based on a tiny amount of information.
Chances are, the guys at Valve know a little bit more about game design than most of you. They know what will work, what should work, what could work and what will not work.
That, and there's the option of...oh i don't know..not using the new items? You're not being forced into them, there's no punishment for not having them. Is it so difficult to say 'no i don't like what the new items might be, i won't use them. I am also aware that there will be people who might like these supposed items. They'll play the game with the unlocks while i carry on playing with my old gear?'
Apparently, the concept of self-control is too difficult for some.
