Yeah for those who haven't heard, Retribution is quitting TOR due to how much of a joke end game is. Not too sure if he'll continue working on Raidranks :-/

Power.

1400-1500 is a good mark to shoot for. Some bosses are going have more movement than others sadly so you will see a variance from boss to boss. Basically get close to 100% hit and then stack power/surge. If I recall I was around 1475ish on Nightmare Pilgrim last week.

Decently geared. Mostly Rakata with some mod/enhancement optimization I'd say. They hit tanks pretty hard, lol.

Lol, I can't believe some people honestly think 8 man is harder than 16 man... Unbelievable.

As far as I know, ONLY the Belsavis daily vendor sells 'em...
