Engineer in ME2 and ME3 for unique stuff like R&D Discounts, turrets and class specific interaction

It made sense for the engineer to have that given that it was something that a engineer should be able to do.

^ Yeah I get that, but I meant scenarios where each Class might have a moment to be exemplified. Like a moment where the cloaking ability of the Infiltrator might come up to take down an opponent in a stand off or the Tech Armor of a Sentinel might help protect a hostage. It might be nice to reference the actual class a player chooses rather than say a brief mention that they are a biotic. (Like Kaiden does when you see him in the hospital)
