Doom1Put a soldier main in OW to learn pharah for a month, then put a pharah main in TF2 to learn soldier for a month see what happens kid...
maybe hot take but the game with 1000x more money in it is gonna be harder to get better at relative to other players cause there's more players and more motivation to improve.
imo if u tell an ow pro to play tf2, them just having the time to play like 8 hours of tf2 a day for a month will get u to at least mid. i don't think like a prem player with a day job can really do something similar in overwatch in a month
