In my opinion Churchill and Croc are still way too good. I just played a an hour and 35 minuts match vs 2 Expert PC's and a Basic one with me.
It takes a way too much time to kill a Churchill/Croc, even with a KT or Jagdtiger or even both...
Don't try it with AT guns cos these get wiped in no time anyway.
These units really need to be looked at again, they are far from fine in my opinion.
What about Brits starting with a Royal Engineer rather than an Infantry Section and extra MP to make up the difference? This would give the Brits early wiring and repair abilities, but they must preserve the squad because they can't build another until the next Tier.

I like this idea!
