The task of what? Carrying the usf late game? At this time usf late game was notoriously bad but it wasn't specifically because of the Sherman, it was a number of factors and units which contributed. Overall the Sherman filled its role as a medium tank quite well.
'Twas always pretty decent, constantly miles better than the 34/76 for 99% of its life, but its weakness in the AT regard was a compound to the problem to USF's ability for AT late-game (and then they didn't necessarily need it if they just played keep-away from the big cats and got lucky wipes
). They definitely don't
need the Sherman for that with the state of the 57mm ATG, Jackson and Zookas right now, though I would rather the Sherman's AP shell at least stay effective enough such that flanking heavies is considered worthwhile for it.
