Sums up my thoughts on this matter. My [options] shouldn't be limited if the opposing player can build 2 heavies.
Again, keep in mind this limitation is for 3 v 3 and 4 v 4 match up were we would see multiple heavies from 1 player, this is not rare. Also in 3 v 3 and 4 v 4s, team players can divide up to mitigate pop cap with OKW. For instance, 1 player goes CAS (infantry heavy), 2nd player will go P4s with Eles and small infantry, 3 support weapons and Panthers and 4th player spams KTs and Obers.
You still haven't answered the fact that if heavy limits are supposed to increase medium play; then why does OKW have no medium generalist tank to play with?
