There are only a couple of capture points that are exposed enough for the Mortar to make sense.
Though if you happen to memorize the routes from spawns you can be very effective (Which is why I have always advocated for Dynamic reinforcement points).
On to the point of Tunisia, it does need work. Demolition can be fun but also supremely furstrating, it is a good idea but I think some stuff needs a rework.
The times between capture points in Invasion are so damn long. They could have condensed it a lot and then just rotated the map to different points to utilize everything.
I do like a lot of the Italian weapons represented, they definately need to improve on the uniforms and really make it all Italian instead of a mix of both (IMO).
