People were comparing the AI power of both vehicles, that's why I responded in regards to their AI power only.
USF is doing fine since the recent patches with 52/51/50/47% win ratios across all game modes respectively. The issue with balancing their 4v4 performance inherently comes down to the fact that Relic decided not to give them stock rocket arty, which is something we couldn't fix as we weren't allowed to put the Calliope in the basic roster. The commanders that bring heavy indirect (Priest, Calliope or Paths with Scotts) will always be meta because of this. UKF has the same exact issue.
You're nickpicking what suit your vision, or you're just reading the last post of each thread. It has always been about overall effectiveness of both units and a focus on DPS at the end because that's the only thing that's go for the Sherman and is easily spammable on a forum@ look the AI damage stat the sherman is better!!!! with 0 care for context.
Now since your so good yourself by your playercard, tell us why everybody here complain about a unit that have far less IA damage and requires to be pack in 3 + extended vision from another unit to be really effective when the Sherman is so far better in that matter. Why nobody complains about Sherman and Pathfinder? Are people complaining about Scott IA damage at the end or something else like its survivability vs reckless panther dives? Do the supposedly superior IA from the sherman really matter during a game? Or is it just an overkill that brings in reality nothing effective you can count on.
Those stats means nothing at the moment since everyone playing USF in 2vs2 is actually doing Scott&Path, 4vs4 the same thing and 3vs3 a joke as usual. Do you think you've achieve something good with the balance when a faction is played building only 2 units supposedly being support type? Do you think the balance is working when everyone is avoiding building riflemen or light vehicle on teamgame?
We're in reality far from a debate around Calliope or Priest vs scott but a build that avoid building any of USF peak. No riflemen, no light vehicle, no sherman, only path, hmg, optional atgun, optional jackson, zook and Scott.
