Judging from DRiller's reply, it looks like they're going to kill generalists and specialists considering they state "TF pros played a fairly different game... (classes and weapons are missing, different game mode, etc.)"
And also it seems they dislike only 5CP being played in TF2; that might be why they tried to push PL and CTF into CompMM.
While I'm happy that we got a reply about TF2, I'm still worried because it's extremely clear that Valve still has an entirely different perspective on what they think competitive TF2 should be. Whether we like it or not, Valve is going to try to turn 6's into prolander.
