WoWhead is saying sword + dagger
And maxroll is saying sword + sword?
Whats the right thing for Outlaw rogues?
sword and dagger
sword dagger for faster off hand attack
never heard of maxroll before
Dagger off-hand but only if it’s actually a decent dagger. Not worth the minimal DPS gain from poisons if the stats suck or if it’s lower item level than a sword.
And if we’re talking Keys then it’s Nightfall Cursed Blade’s Cudgel > anything else except on bosses.
This was true last season because Killing Spree benefitted from both weapons, now it’s MH only.
It also makes dual wielding actually historically accurate 
u use dagger offhand for the offhand energy procs
