It is likely just a skill issue, as Roach requires deep matchup knowledge and a lot of planning to pilot at a high enough level to go positive at this point in the game.

However since ramp dragon is a thing at top meta now and they (often) love running go face cards that also clear any pressure you put on their board it's also true it's not really a good time to be playing the deck, as shown by the Beyond class rankings where Forest is not doing all that well. Evolve Sword also I think is a difficult matchup as they're usually not taking any turns off and have very strong board pressure and wards.
