Back in TBC, bloodlust / heroism was a group only CD / buff. It was strategically used to buff groups at different times depending on the needs of the raid and the dps requirements at certain points in an encounter. This made the usage of hero/BL much more strategic and made fights more interesting with it being used properly.
Now as you know, its a raid wide CD that you can use 1 time per encounter.
Should Blizzard revert bloodlust/hero back to a group only buff to bring back some of the strategic gameplay that it provided?
