Many ukf player tech to 5 men early on now.
5 men IS in 1v1 2v2 is enough to delay bren upgrade, especially against ost
Lets assume you are right, then yeah IS would be one man more for slowing down tech a bit.
What I tried to say: Someone said lets buff USF mortar to Ost level and move howitzer to doctrinal. Vipper answered that would be OP versus Ost because of small squad size and static gameplay. But on the other side who is more static than brits? Completely static mortar and IS squads that seek cover like a magnet because of negative out of cover modifiers and mid-long range weaponary plus small starting squad size (which can partly changed via side tech). Brits are the embodiment of static in CoH2.
I just wanted to say you can't claim an argument for just one faction if it is very similar or even worse for another one.
