Valve cares for TF2 ? Why did it take them so long then to nerf it? Not that its actually nerfed now in the real game...
well they probably spent the time making this beta because they are probably sick of doing this, internal testing, implement, steam forum complaints, change balance, test, steam forum complaints etc etc, this way, they can externally test the new nerfs, map changes etc (messing with granary's layout is something i would have to implement without serious testing) and get better data to make the normal tf2 game better. Plus, please remember the TF2 team is small,
really small.
I for one can't wait for the day when i can run around as scout and not be slowed down by some nub a million miles away using a natscha *cough* pete *cough*
