Agreed. No use of getting a KT now since they didn't buff its frontal armor/side armor. Slow turret will make it so easy for 76, 85, Cromwell, etc spam to own it now. No shrek to protect it either unless you turtle a place with toy rockets around it. 2 panthers or 3 JPIV are a better choice.
On the bright side they are reducing the fuel cost of KT which I think most would agree is overpriced right now - so they are getting that right at least. As much as I am for getting rid of Volks blobs I really do think they need SOME kind of hand-held AT... its basically a core mechanic of the game and needed to protect OKW's expensive tanks. Assuming most of the preview patch goes live eventually I'd be happy with going with some people's suggestion of giving OKW a new Tank-hunter team unit, something with really terrible AI but fills that role well. Either that or giving Volks a second upgrade package with PTRS-like weapons to let you diversify your force as needed.
