It would be interesting to hear from the actual players that played the Brits last weekend or played against them. However, they always seem to avoid these threads like the plague.
Perhaps create a thread especially for them?
At risk of sounding like an elitist douche... most top players feel like they're wasting their time explaining issues in detail when rank 1,000 fanboys come and tell you why you're wrong because some numbers on a spreadsheet theoretically MIGHT make their argument valid. But theory and practice don't always line up.
The biggest issue Brits have at the moment, in my opinion, are their difficulty in killing tanks (lack of snare) and difficulty in doslodging HMGs/pushing into green cover (lack of indirect fire).
Fix those two, and you'd probably have a decent enough faction even with current stats on units. If you buff other things instead of fixing inherent game mechanic flaws, you're going to go back to a gimmicky UKF crutching on overpowered stuff like Cromwell spam, Centaurs wiping like crazy, Land Mattress erasing armies, Commandos 1 shotting anything they come within 10 yards of, etc.
