Yeah, except if you put them in a match and compare the performance of 7man shrek cons and 5man LMG42 Grens vs PIATs 5man Tommies and BRENs 5man Tommies, the former are better.
Solely because they got gutted to accommodate their shit awful design decision to make bolster a global. I recall vividly when tommies were just straight up better grens at 4 men and monsters at 4. Now they are a joke as 4 men and alright with 5. That's exactly the point in trying to make. Either 4 men are trash so 5 men are balanced or 4 men are worth the cost and 5 man tips them way over the edge. You can't reasonably balance such a power spike. Cons extra model either comes from a full tech or 3 combined side techs and 2 buildings THEN takes a munitions cost AND their only weapon slot and it still had to be toned down by removing the cover bonus and lowering the reinforcement bonus. Increasing model count is such a colossal upgrade its hard to balance and has caused nothing but problems balancing tommies from the word go.
Also brems got heavily nerfed because--go figure 5 man double lmg infantry with elite target size and bonus durability in cover was fucking Overpowered. Again a result of the global 5 man upgrade
