So just because the test shows grens do not suck as much as claimed by lots of wher players its a biased test.
You claiming bias on this test, when you only see up on axis side and op on allied side invalidates your claim entirely.
The test was to show 4 men grens vs 4 men sections. To show if you do not upgrade to 5 men what would happen in the inf department.
To me sections are fine. Brits have great versatile infantry. I always use bolster. As UKF you must play like ostheer and use the full power of sections AND mgs. You just can't play them like USF or Sov. Sections can easily carry you to next stages of the game and remain your staple infantry. I can't imagine a scenario where realistically speaking you don't put sections in cover where they are boosted. In their "natural" circumstances and when properly supported, they rock.
When it comes to testing - one should test all scenarios and only then draw conclusions. You can't set up a test in probably the only scenario when a given unit loses and use it as an argument to boost a unit. A risk of unbalancing is too great then.
