to be perfectly fair although your problem is probably a network one and not a hitbox one the projectile hitboxes in tf2 are retarded as fuck.
first of all they all look like this:

no matter the class. the scout has the same hitbox size.
not only that, but they don't turn with the playermodel, instead they are locked to the xyz planes of the map. this is demonstrated in this picture:

this means you actually have a larger target if you fight someone at a 45 degree angle to the map axis than if you're just doing it dead on.
this is why the huntsman has a huge headshot box. because the box is bigger than the model.

(i killed the pyro with that shot which clearly missed him entirely.)

we already have 7cp
its called granary

new hats yay (not yay)

people like you who don't understand why the 6's meta even exists make me sad
no its not because all the 6's players got together and arbitrarily picked 4 classes we liked the best
valve made scout soldier and demo the best classes at switching between offense and defense quickly
medic is required and better at healing than engineer so there's your 4 classes
we dont hate the other classes (except pyro fuck pyro), but we do think its retarded and annoying when they slow the game down

i had a tick on my balls when i was young and it had been on for a while so i went to the emergency room cuz i couldn't get it off and they decided the best course of action to get it off was a red-hot needle. AND THE NURSE MISSED.

Please do one between sigafoo and the 7v7 format pls

where the fuck does this man get money from to do this shit

Started playing this game back in 2013, although I do remember playing it before then but I don't remember when. Played on shit servers for a year until I found this cool pub community who had their own dm server called The Pit. I played on that server for ages until people stopped playing on the server (it died in mid 2016 but I had stopped playing on it before then). In late 2015 I joined my first HL team, Rhymes of Reason. This team was so bad it made me want to die, but I was an idiot and new to competitive so I kept playing with them. I was then asked by the heavy on the team if I wanted to play demo in 6's, which I did. That team stayed together for 2 seasons of iron before dying. Moved up to steel not because I got better but because Iron died (lol). Played 2 seasons of steel, got bored of playing against shit players and being a shit player and decided to play my first season in open last season.

Dr Phil med for LEGO what is this blasphemy

Also, don't pick someone up for your team if he's known to be a toxic scumbag, for one ur team will probably be dead within the week and two now ur known as the guy who has [insert scumbag here] on ur team.

because buzzfeed news puts a spin on everything in order to push their agenda. i can say the same for breitbart or infowars and it would be just as true. buzzfeed gives zero fucks about producing actual quality content. that's why they're basically a scam. they produce shit 24/7 that's designed to do nothing more but get clicks. the news thing is probably only there so they can say "no look we're a legitimate news outlet we report on things" even though its meaningless trash. /rant

I think he's playing devil's advocate and explaining why people enjoy random factors in games.
Of course the example he gave (speedrunning) is not really applicable to TF2 because in speedrunning you can always start a new run, whereas in TF2 u can't restart grand finals because of bad rng.

Buzzfeed News is about as legitimate as that Nigerian Prince who needs money now

This man is a god.
