I continue to believe the special forces nerf, while it might have been OK for immersion, is bad for gameplay. Special forces simply aren't worth the research any more. The time and production you could spend on them is better spent elsewhere.
If I need to invade Great Britain, here's my order of priorities:
- Fighters for air superiority
- Battleships for naval superiority
- CAS for support
- Regular inf + telephone mana so CAS has enough time to secure a port
- Tanks for post landing
- Carriers for naval supremacy
- Air doctrines for air supremacy
- Logistics support companies
- Shore tanks + telephone mana to assist CAS in securing a port
....
25. Naval doctrines
26. Marines for slightly less penalties while supporting CAS to secure a port
I'd rather spend my research on almost anything rather than marines or other special forces. They don't justify their cost now.
