Conscripts are hella more durable than panzerfussiliers.
Conscripts dont cost 290 mp and 90 munitions.
If panzerfussiliers are spammable, then sections and riflemen are as well. Because they cost the same. Cept IS and riflemen are significantly more durable, and for 30 more munitions, can dual equip. And win hands down vs panzerfussiliers.
2-3 volks and 4 pfussies is valid BO.
I've played it myself and I've played against it many times.
When I see USF player going for more then 4 rifles, I'm just laughing for the short game and free win I'm about to score, exactly the same if someone tries to get 4 or more tommy squads.
You know why?
Because there is something more then just initial cost, for this reason 10 con strats work, but 10 gren strats are suicide.
There are tech costs, there are model reinforce costs(which both, rifles and tommies have considerably higher then pfussies), there is synergy with other units, that other units costs, timing etc.
Yes, pfussies are spmmable, rifles and tommies are not for the reasons above.
