sagethe possible difference in balacing the game for 6v6 and 12v12 is negligible. the game should be balanced around the higher skill play anyway
the difference in balancing the game for 6v6 and 12v12 can actually be major, for 6s players anyway. 12v12 players can be more flexible because people don't exploit broken shit to the fullest extent, but competitive players do, so when I say "balanced around pubs" I more mean "valve has looked at certain weapons/classes and said: this is good enough for pubs"
i definitely agree the game should be balanced around higher skilled play, which is what valve are slowly moving towards
Makexcept for the fact that if u go watch the in game dev commentaries they also acknowledge there that certain classes are generalists and will be viable on both offence and defence.
i've seen all the dev commentaries before. none of what you just said is in any of them. are you referring to this
"The Demoman is the most versatile combat class capable or rapidly switching from strong offensive pushes to defensive area denial."?
because thats pretty different in intention to what you said. the word "generalists" was used by robin walker in a separate interview to describe why demo and soldier were a pain to balance, as in, they werent happy with that situation.
"Some classes are useless most of the time", as syph says, was obviously never an intention of valve if you look at how the pub game is actually played, and the unlocks they've given engineer/heavy (eg gunslinger and gru) to try and make them useful more often.
