so well, they dont have a p4IST, they dont have Assault Grenadiers, they dont have armoured cars, ....?? (yes they do!!)
i could go on and dont tell me that those units are uneffective
you dont get it,do you.
Luft gets falls with buffs,which are > than any pgrens you might field
SE gains flamme grens + hummel +inc. strike,inc. mines etc. > stronger than any AI options TD get
so tell me,what exactly you dont understand? Do you wanna claim that TD have equally strong or stronger AI means as other 2 doctrines? Am I claiming anywhere that they should get em?
P4ist isnt nothing amaizing as AI,yes,he is nice,but eats a lot of fuel,and when there are few atg's on field,he is more or less useless,thus there is a reason you see so many of them fielded

Assult pgrens are still pgrens,so I mentioned them,dont see why you mention them

armored car is okay,but for the same ammount of fuel he eats,I can field several normal scout cars with no upgrades,that will kill atg equally fast+wont be so fragile as 1 armored car +can cap. So dont rly see reason to take him.
