I donr think so… We dont play with an engineer because there is no need for an engineer anymore, and it makes the game more open and more fun.
We werent skipping an engineer because of some barrier glitch, we were skipping him because what is the point of having a character in the game whose only usefullness is a slight decrease in cost and repair?
Engineer is like a JD now: used to be mandatory, now it is really option, with some but very limited usefullness over other characters…
