No idea, but I am sure they will have some use for it. I am a bit pvp focused atm though and that is how I have been looking at classes.
Also, I sure as hell hope that pve is more intriguing than many variations of a tank and spank. Avoiding damage has always been a DPS responsibility and taking cover sure as hell classifies. A few key abilities of IA/smuggler also involve cover. I want to be able to find cover to heal as well, just like in real combat.
