Seems to me the problem is more player meta than it is job/stat changes. Seems SE is moving SB away from the "everyone is AE deepz" speed running meta of HW, and moving towards a proper group dynamic where enmity staying on tank IS A GROUP EFFORT. Used to be everyone goes HAM, and tanks clown on how easy enmity is, even undergeared, gimped, 5+ levels lower than DPS, wielding wooden spoon, uphill both ways, always in DPS stance, etc. Now holding aggro is harder and DPS have to actually watch their own enmity meters. OMFG, the horror!!

Enmity on tank is a group effort. All SB is doing is reminding everyone of that.
