I have a problem with the sherman WP. With all the buffs the dozer blade gives, there is basically no counter to the WP shells via AT guns. If you fall behind ingame so your opponet has a tank first, the ability just shuts down AT guns. It isn't like regular smoke where you just attack ground through it and use your skill and a bit of luck to guide your shots. You're forced to move your AT guns, and when you displace your at guns, that's when they get cleared.
I really don't think that the HE sherman requires this many buffs or any, I don't see why an armor piece is being given a hard counter to its intended counter, and I don't understand why we keep trying to make OMEGA commanders which make every commander pre reworks obselete.
Power Creep.
Currently people often skip Shermans for Scotts, so they buff them through a doctrine, to make them atractive again. By atractive I mean abusive in some way, that's how the game is nowadays, you only go for the most broken stuff available.
Don't worry, it will likely get nerfed once it goes live, if it proves too strong, within a week.
