trogHe thinks it's stagnant because we don't use different weapons.
and because he has no fucking clue what a good competitive fps is comprised of.
the less "blind guessing" there is the less variance there is in what you can expect from a given push/hold. this forces players/teams to simply play better and over time raises the skill ceiling.
once you have to start trying to guess what secondary both soldiers are running, on top of the possibility of off class shenanigans you havent spotted yet (spy, sniper, delayed heavy, etc) are coming with a push, the game is going to be incredibly frustrating.
it seems like the folks at valve want 6's to play out like some promo video where you have a conch soldier running dh and a quickfix medic flying in the sky with him instead of having a quality competitive fps game that's continuously raising the skill ceiling by steadily improving with (mostly) vanilla weapons. quake didn't need gimmicky shit, why do we?
also let's be real, valve could use 3 months of manco store profits to host an international-esque tournament and tf2 would be fucking FLOODED with tons of new players, sponsors, etc. and the game would actually get a legitimate shot at being a "real" esport. they could even do the compedium style thing they did with dota so future tournaments would be totally crowd funded. but they wont.
