ratawarI would also like to read some stuff about this as well, I add: 6s environment when it comes to engaging in fights as Scout.
if your finding it difficult to dodge in 6s its most likely not actually your movement and instead your positioning since if you were playing high ground then you wouldn't need to move unecessarily. there are 1v1s that still happen and thats more about taking fights that are advantageous for you so bad movement wont matter as much.
swampcreatureMainly 1v1 fights for me as Scout against any other class. I find it difficult to dodge projectiles/hitscan and hit my shots at the same time.
mge helps a lot with that, also playing as soldier or demo and playing against a scout lets you see which shots are really hard for you to hit if you are paying attention to their movement which you can try to replicate. a lot of it just comes down to trial and error though
