People often make this comment when they talk about reaper in organized group content fractals,raids
They say other classes outperform reaper coz boon uptimes favor other classes more when compared to reaper
But... The trait "awaken the pain" gives extra 1000 power for 25 stacks of might with some condi dmg too... And include this with extra 600 ferocity in shroud form. Afaik, no other class gets this much ferocity and extra power and to top it off... Reaper cleave radius is huge
And gravedigger doesn't have a cooldown when the boss reaches 50% hp (combine this with soul Barbs while exiting shroud) and gravedigger becomes a relentless nuke
But still ppl consider it less efficient in organized groups...
