Yes, but that doesn't change anything really. You'll need 6.5k weapon (or spell) damage to make it do as much damage as it does now on live and it will still be flame damage. It's won't be better for stamina than it is now unless you go over that 6.5k.
All proc sets will now scale with various stats, check the PTS forums for the patch notes.
For group you use the Harpooner’s Wading Kilt.
