Having the 2nd boss in the raid be dissproportionatly tuned is not the correct model. Styrak and The Terror should be as tough as pre-nerf DG were. The DG should NOT be the most difficult enounter in the raid.
I get that, and actually agree. But the fact is, DG was where it needed to be in the original version.
The other fights (most of them - Writhing Horror, Operator, Dash'roode, Titan 6 maybe) were disproportionately too low of difficulty.
