Found this vid on forums of the first bosses in Donova operation (new one in 1.2).
Only 1 bug currently which doesn't allow for some aoe to be cast onto the ground but apart from that it's a solidly good boss. Enrage timer is apparently pretty fast though so it's more of a gear check for this op than anything else.

Also these bosses drop Rakata tokens which have now been added to the game, as well as black hole commendations and exotech (this was on the 'story mode')
