I'm not sure what you are playing but mobility is the name of this game from my experience.
If you're really staying in front of a bunch of static units instead of trying to flank or bombard them then there's something seriously wrong with the strategic genius behind the screen.
Same went with the British in CoH that got their Fireflies with Hull down as well as the Cromwell Command Tank that buffed their reload.
You don't stay in front of them, you either go around them or hit em with arty.
That's fine and all, but turning a JP4 into longer range elefant is a bad idea
There's currently a thread about how strong the hulled down Panther is, and that's without off map arty or HEAT shells that also increase AI damage.
Then yuu consider the KT is an okw stock unit and you ould have a literal bunker.
In the preview tanks no longer need infantry to hull down, and it's only a click to disengage so mobility won't be a huge issue as you can just creep forward with tanks that are already extremely durable...
