I think it's better to remind you that UKF also happens to have constantly lowest WR in 4on4 & 3on3. (apart from 1 or 2 weeks of exception of second to the lowest!)
https://coh2stats.com/stats/week/1617580800/4v4/wermacht
but according to stats, ukf is 2nd best allies in 3v3 and tied with ost as worst on 1v1 and statically close in 2v2
didn't ukf got a recent buffs in last patch. i don't think ML so far is an indication, top players playing for money has no time to experiment.
in my 4v4 rank 400+, i got matched with 500 ranked players, i see plenty of ukf. my 4v4 rank don't mean much but..
imo as i said to reduce churchill main gun damage to 120 and revert the pop cap nerf. that should give ukf a longer late game while maintaining churchill AI damage sponge role
