I have noticed this to in 8 man denova, only recently since 1.4 came out. This better be a mistake, otherwise this guy is getting too hard to kill. A lot of people still havent killed him yet, and making him harder isnt going to help. My guild is so fed up to the point that alot are probably just going to just give up with the game and end their subscription. Bioware really needs to pay attention to the common gamer out there, rather than the elitist ones. If swtor wants to stay afloat, there needs to be some changes with the difficulty in some of these operations.
^ This. We gave up after a few attempts because running with some mercs means on a 12 second timer we're going to miss a lot of those shots. Couple in the fact one of our guys internet connection was bad just for Denova but literally a second or so, and that's 1 person unable to interrupt.
