I mean i dont want to be that guy but the engineers are literally the 2nd thing you unlock in this game progression wise and if all it takes is those “Critical first few games” to make you leave the game it probably just wasnt for you. by this time at least a couple people on your team SHOULD have engineers unlocked now whether they use them or even have them in there squads is a different story
Pro tip for the early game: if you have a engineer slot unlocked in any of the squads you do use but you dont want to use the engineer squad just swap out the engineer in your engineer squad for a rifle man and bam you got a engineer you can now use in any squad and you dont have to spend an order on it.
