As for the sappers, I knew they were engineering units. I know I’m a bit dense, but not that dense 
.
Medics are the equivalent of assault soldiers, I understand that perfectly, but sappers don’t have assault weapons, and using them just to establish rally points… well, from my point of view, the advantage isn’t proportional to their use.
Once the rally point is established, what do you do with the sapper?
Especially since it’s a squad for new players, and besides, you don’t unlock sappers from the start.
The point of adding a sapper would be to equip them with an assault rifle and remove a medic—basically, do it like the premium squad. Do you see what I mean???
