Rough time as UKF, looking for build/tips ELO 1200

Hi,

So as of late, I'm having a rough time as brits and I don't get what I'm doing wrong. I've played COH2 for 1500 hours and a bit of COH3 but there is something I just dont get. I usually play Canadians or Poles, sometimes Ozzies, but still I get wreck by P3 blob, or other blob strat. I feel like Inf section kinda suck. Idk.

As Can I usually do

Vs WER:

Sapper - Inf - Inf - T2 - Can - Humber - Can - AT - Inf training - T3 - Mathilda - Nades

Vs DAK :

Sapper - Dingo - Inf - Inf - T2 - Humber - Can - Can - AT - T3 - Mathilda - Inf training - Nades

As Poles the build stays similar but replace Can by Poles. I sometimes build MG but I feel like they get run over really easily... What do you guys do ? What are your builds ?

Thanks, It is probably skill issue tho lol
