First of all, i love fury it's my favourite spec from all melee specs ingame since tbc. I'm casual/semi hardcore(2.1k this season and 2.1k xp as arms in 3s back in legion) but i think it will always be in the shadow of arms's mortal strike debuff in PvP, i know there is some viable comps for fury but they will never be that good like arms has.

Do you think this will be different in SL?

I usually do +15/16 m+ and play some arenas running arround 2k without putting too much effort but i would love to be able to do it as fury which right now is pretty impossible.
