One match in which the Ostheer player did not produce the adequate counters (no snares or Tellers to slow them down, nothing to spot for the StuGs to use their range advantage, not getting at least one Panther to use tank the damage for the StuGs, not using Pak 40s for their stun rounds) doesn't really prove anything.
That said, it will very likely receive a very minor price increase and one additional popcap (up to 19) for the final patch to better match its "performance" (mostly having 1400 hitpoints and decent armor). I personally think Churchills are only a problem when 2-3 of them are deployed simultaneously.
Instead of Churchills being used tactically as a damage sponge for other units, at the moment they are mostly just being spammed on masse to overwelm the enemy with their sheer number of hitpoints alone, so hopefully the higher popcap will make it very hard to build 3 of them and still have anything of an army left around them. Without support, they should be easier to counter.
Yes sounds good.
Churchill still have good pen to damage tanks from the side(rear) for 160 hp. I think that is heavy for AI tank.
I rather keep the 18 popcap and reduces main gun to 120.
Extra 2 popcap you can still put out 2 churchills.
Ukf already have FF and Pak and Piats/Snares.
