Yup. I'm playing "Tank Warning" (great scenario btw) as Germans, and my top priority is to keep Pz-IVHs out of any possible hull down positions...and if at all possible, hit T-34s of my opponent when they are in their temporary hull-down positions while moving over the crest towards me. Sounds like an impossible combination, but with forward slope positions this can be achieved. In one turn I managed to kill 15 T-34s while losing only 1 Pz-IVH...
Unless these tanks were specifically designed to fight on forward slopes, I consider this modelling of hull down, with virtually enhanced turret hits, to be the greatest weakness of the current game engine. IMHO, of course.
