4. Why didn't I have the personal cover shield in the 1-10 range before I became a sniper?
5. If taking cover is a basic core mechanic for these classes, that you are learning to use right from level 1, why do people keep saying that scoundrels and operatives are never ever supposed to take cover? Should they be?
4: Cover screen is only for Sniper/Gunslingers. Not the other AC... so it is not granted until you learn your Sniper/Gunslinger AC.
5: They really shouldn't use cover, because they are a close range 'moving' attack class. Going into cover would negate a lot of their skill effectiveness, as not many cover nodes would actually be right near an enemy to be of any use. Also, they do not get cover screen, so crouching in the middle of open ground, provides no real benefits.
