Actually the Expedition is just a fun in the game for players who have free workers and have nothing to do with them. Even a “Demolition Squad, a team of Veteran Commando, a Heavy Bazooka, and a Flamethrower” doesn’t worth 2 days of 3 or 4 builders, especially when you know that this Demolition Squad does nothing with an lv 190 player.
The idea of expedition is nice but similar to university it is implemented in a wrong way and wrong time (for most of players). By wrong way I mean it is a part for having more fun with the game but interface is too simple, it doesn’t give me any sense of expedition! It’s similar to opening a trade good box that take 1 days instead of 1 min. no special artwork or map exist just a simple list! And by wrong time I mean, for now most of players are busy to complete major upgrades to be ready for atomic age and no one has free worker for this funny parts of the game.
