I agree with you here to some degree. Although I think a lot of people will not be able to complete this content. Sure BW might make it easier in the future but the damage has been done.
Yes I agree with you I think the more casual Op people MAY struggle with the 2nd boss (I haven't gone there with my casual team yet) as there's many mechanics to it., but for the 1st and 3rd boss is I think OK BUT we have to wait and see whether people can pound through the 2nd boss.
Its not a perfect system but I guess Bioware's was also hoping people will farm the new dailies for the new Blackhole gear which may help them clear the content.
