- Offhand melee swings
- Whirlwind
- Raging Blow
Meanwhile, the stats from the Specimen Slicer will increase both main and offhand hits to the point where it's more worth it to get the stats.
Bloodthirst will only hit with the main hand weapon, as will Slam, Colossus Smash, Heroic Strike, and Cleave. I can't comment on LFR Gurth in the offhand, as I haven't heard anything about it, but in general I've heard it's best to have Gurth in the main hand for all situations, including over a 410 Specimen Slicer which would be BiS for offhand if I remember correctly.
