another thing: I've seen a lot of newer players suggesting that the movement speed thing "created" the role of the pocket scout by contrasting 2019 tf2 with like 2010 when everyone was just much worse
by like 2013-4 pocket scout was pretty well established on almost every team, way before the movement speed buff. teams of that era had probably the most egalitarian heal spreads in tf2 history, it would be like demo and pocket 25%, pocket scout 19%, flank scout 16%, roamer 15% or some shit. if anything, the changes have stratified pocket and flank scout even more and basically fucked over the latter. that's why I stress that scout isn't OP, pocket scout is.
