I don't see any reason they shouldn't have to upgrade. Even if it's free I don't see why it's okay with them to drop with all-range effective weapons.
They get a snare, it's not like Paras have every advantage.
Paras have the advantage of durability, being the most durable usf squad but also the ability to reinforce on field via beacon. Falls are made of glass but hit like a truck. They do not infiltrate so there is no requirement for the upgrade. You might as well just make them drop in slower for all that great" change would do. I see literally no purpose in it, especially if it's free. Should commandos have to upgrade? I'd say that an extra man and the ability to reinforce if done well is equal to long range dps no?
