I hope that there is going to be some serious weapon rebalancing in the MM patch to bring out some legit alternative side options to stock / current meta (example ubersaw, basher, equalizer) without making it feel too gimmicky.
While stuff like tide turner, huntsman, mini sentries etc wouldnt be viable in competitive against good/decent and probably not even low teams, would allowing them in MM bring something to the table or just encourage people to use gimmicks or whatever you want to call it. Depends on what the tf2 dev team / valve wants; is matchmaking going to be a way for people to play 6v6 in whatever play style they want - maining huntsman/demoknight/pyro or are they going to encourage people to run the current 6v6 cookie
Curious to see what will happen, definitely looking forward to playing/testing banned unlocks in matchmaking.
