I don't agree with that argument. PE probably had the most global upgrades and they weren't better for it.
That being said, I also share your feeling that there is a lack of strategic depth but I find it lies elsewhere.
1. The simplified cover mechanics.
- There's no need to deny cover, just walk up to the enemy.
- No need to push infantry out of cover with light vehicles.
- Fire and explosives used to deal more damage to units in cover, less in negative cover. That was a nice trade off.
2. The awkward s-mine placement.
3. Doctrinal Forward HQ.
4. Doctrinal tank traps.
Still, it's early in COH2's lifetime and people are still finding out new ways to play the game and nothing prevents Relic from tweaking points 1 and 2 at least.
