By the time they arrive, rack will be open. Furthermore, if they arrive on the front lines, last I checked, the upgrade takes some time to complete... so stop with the BS "oh no, USF got buffed a bit" [screeeeeeech]
If you want to have a debate in forum pls avoid this type of remarks.
You remark are also completely off mark.
1) This has little to do with buffing USF since it involves doctrinal unit, it has a lot more to with buffing one of the most popular USF commander which happen to be airborne.
2) Upgrade does not only mean the airborne paras get "free tech" (which one might or might not have teched but now one has even less reason to do so) bazookas, they also get:
Camo/first strike bonus
the ability to upgrade AT in the front-line without having to return to base
The fact that Ar Paras do not come with support make far more suitable for front-line drops.
In sort the change makes Ar Paras a move attractive and that support paras and will lead to even more dominance of airborne commander over reckon which is the opposite direction that this patch should be aiming. Airborne is the USF commander that need buffs the least.
