Don't be grumpy Snutch.
To be honest, all of the fights were extremely difficult, I'd even say that some required a huge helping of luck in addition to skill. The damage was never tested on 16-man, so I'm not sure if it was intentional on Bioware's part, but Olok and the Cartel Warlords especially had 1-shot mechanics that were extremely difficult to recover from if anyone made even the slightest mistake. We still had pulls on OIok where people would die without anyone making a mistake. It took us a long time to figure out how to effectively 'save' people before they were gibbed. Hopefully with the release of the videos it'll become more apparent.
