ScubaSquidboomerthere's too many variables to answer a question like this
the way i see it, and this is just personal opinion. there is alot more of a chance of a scout winning the battle solely for the projectile vs hit scan weapons. projectiles can be easily dodged and avoided as long as you are in view of the person firing it (in most cases) where as even if you are looking directly at a scout its alot harder to be able to dodge his hitscan because the damage is instantaneous. with the added movement speed and double jump a scout playing from mid range distance is more likely to win the fight even if the soldier has the height advantage
its really not
when you say that projectiles are easier dodged than hitscan thats kinda bullshit/an opinion presented as fact because a lot of soldiers who are really good at mge are good at soldier v scout because they just know which splash rockets to shoot to deny the scout getting close to them without taking damage
different players with different movement-styles and different sensitivites all present different ways of dodging and aiming that really make the arguement about which one is easier to dodge a pretty useless one
if theres no timelimit a scout should literally never die to a soldier because hes faster and can just stay at mid+ range where his weapons/movement are way more efficient than the soldiers and rape him
generally speaking if you have to get close to a soldier the soldier should win
that being said you dont have 40 seconds to chip away a soldiers buff in a game, he will have his team show up
this is why these questions are pretty fucking stupid to argue about because tf2 doesnt happen in a vacuum, the closest thing to that is ammomod (mge) which still has a ton of easily abuse-able mechanics
a huge part of being an effective scout is being able to not miss while you have shit loaded and are closing in on a soldier
watching people like yz50 a few seasons ago or clockwork now who can literally shoot as fast as possible while dodging and never hitting less than 60 is really cool and impressive, which i guess is why so many people think of them as the top dm-heavy scouts
tl;dr you guys should argue about which color is the best or what is the best kind of weather because it would honestly be a more logical/relevant arguement
