I think the game is easily exploitable with concealment activated for all units, and thus, frankly quite boring

I'm playing on commander / iron man. Right now, mid game and only lost a rookie.

Not trying to sound pedantic here. I played the first over 100 hours, long war and all.

The last 8 missions I played went like this.

1. See where the objective is

2. Find the path that takes me there, closest to a map border

3. Sneak until I get to objective

4. Take a good cover position, if possible, high ground

5. Rip the enemy to pieces with kill zone on my sniper (over watch on my turn) and a plasma grenade

6. Wait a few more turns, so more groups fall into my trap. Bait them with a highly armored ranger

7. Extract

I really wish concealment was only available to soldiers with this ability. The game becomes very easily exploitable like this.
