Oh God...

Do they have to?

That sounds like a BF compensation. You'll end up running around a corner and see a particular enemy and end up getting a nasty surprise. If it was nades or the infection gun, or something mundane that should have been in the game to begin with then it wouldn't be as bad as it sounds...

I like the way that the characters in the game all have their own specialities and you have to change to combat something evil the opponents have done.

Edit:

Just remembered BF Heroes. Anyone else got an uncomfortable feeling as to where this will end up for TF2?

having same convo on Op2 forums, would link it but I fear the wrath of the no-advertising squad

I can't wait to see where this goes, but at the same time, I'm very apprehensive since they successfully ruined the demoman's primary, the sniper's quickswitch, the soldier's rocket dmg spread and made the pyro overly powerful ...
