Returning to the game after a few years and have some questions about Imperial Agent class.

So after a few years away my buddy and I have reinstalled and are getting back into the game. My main character is the Imperial Agent. Most of the abilities are close to what I remember and looks like they went the WoW rout and did away with the talent tree, which is sad. I just want to know about some of the big changes I should be aware of for my class and the general game. The obe thing I really want to know is if IA can still deploy their own cover. I couldnt find the ability, used to be a shield generator you put up and entered cover that way.

Any help would be great. Edit. I am playing Sniper, marksman
