That is a very good point Ninji.. But it annoys more the mapping community of TF2Maps then Valve to see recompiled Maps... We don't really care about what Valve thinks of their updates after releasing them but we care about the fact that we are going to get tons of recompiled valve maps on this website and it's a thing that we don't allow.
That's why this update is somehow disapointing cause it affects the community, not valve. Instead of spending their time making useful new maps that valve has a tiny chance to accept (still biggerthen recompiled valve maps), they spend it changing stuff in valve maps! That's why it was a bad idea to release them...
If Atleast they made a random map that would never get in TF2 and include everything that a map shoiuld have in it (Areaportals, skip, hints, models, brushes, etc...), everything would've been better!
