Still not allowed to start threads so I guess I'll have to put this info here.
So basically, I went on the PTR and tested out the scaling on Lord Blastington's scope of doom, Currently, the tooltip reads that it procs for 68 agility on my 24 hunter. Unfortunately, it seemed to be bugged on the PTR and wasn't proccing at all but from my experience at 90, I'd say this procs roughly every 20 seconds. (The buff lasts for 10)
Dancing Steel will likely proc for about 60 agility. keep in mind that you can have 2 of these buffs simultaneously. Rogues will likely see big eviscerates but very few big ambushes since the proc won't happen until after they've opened. From my experience at 90 I'd say rogues can expect to almost always have at least one of these procs up at all times in the middle of a fight. Probably not going to be as consistent at low level however.
Frankly, I don't care enough to go test out a ton of enchants on the PTR and see the exact numbers they scale to, but my educated guess is that P2P accounts will be able to get enchants that are about twice as good as the current BiS enchants. so instead of +9 agi to feet around +18
But who knows, I'm just going to wait until patch day to find out.
