For every RT pbem I've played since it came out that had uberpanzers, I've played half a dozen with PZ IVs, StGs, T-34s, and Su-76s. Realism is great and I love it, but I really enjoy something different from time to time. I loved AK because of all the wonderful early war AFV's. So, I'll keep clamoring for E series Panzers, Pershings, T-29/32 types, Comets, Centurions, IS-3/4/7s, and so on because variety is the spice of life.
