Unless you had fury warrior and a DK as DPSers in 10 man raiding group - given how borked 10 man loot is I've yet to see a single drop for my ret offspec (not to mention I do hate raiding as RNGetadin - why should I be forced to do so? I'd rather taunt at 4 stacks of whatever). Of course I think I'd be forced to run DS heroics ad nauseam to have around 377+ ilvl offspec... But blizz should make it so that at least 80% of each tier will require 2 tanks - not like T13 where almost half of the fights will be solo tanked...
