Now for my impressions.
Hetzer; Love it, would be better with more zoom. Front armor is VERY effective, traverse is annoying, causing a delay in engagement, but has not affected the outcome of any engagements for me thus far.
Jagdpanzer IV; again, love it. Gunsight is bugged, but I still got 2 kills before being force to RTB. Cannot look around from the commander's position, very annoying.
Jagdpanther; have yet to try it, felt informing Pyro took precedence.
Yaks;
