It's slightly offtopic but as Hybrid it was pretty surreal to read forums after the Fire Mage nerf, where Mages started talking that fire spec is broken and totally unplayable now, yet they still did more Dps than Ranged Hybrids.
I think the Problem here is that Arcane is way too strong, not that fire is too weak.
And again, it was example to show this issue, not a conclusion.

And dont compare items with and without sockets if you dont know how sockets are valued (it was -20 primary and -20 secondary for one socket, regardless of color or socketbonus in cata btw)
Compare numbers on worldoflogs -> win.
Blizz knows exactly what it's doing ... If shaman dps has been a bit low, then that's because they intended it to be low. From what's i've seen enh is slightly ahead on elem. So in retrospect, a 10% (instead of 5%) lightning bolt buff in our tier 14 2p had made more sense.
Since they didn't ... it was probably enh it's time to shine a bit ;-)
I doubt that, else fire wouldn't have been as sick as it was till it got nerfed ... and there are plenty of examples from the past as well. They know what they are doing within certain limits, and still they got surprised by how people do bosses or change the rotation they had in mind when designing the spec.
Let us see, napkin math:
For T14 Normal (~496 ilvl) according to SimC we got 6.491% gap favoring Enha. Now, in T14 Heroic profile we'll see gap around 7.384%. Scaling difference is pretty low for me, but if our setbonuses will be equal, than in 5.2 BiS (or 5.3 with valor upgrades) gear we can get 10%+ gap.
10% gap over 13ilvl is not possible.
What he probably means is when class A gains 13ilvl (eg500-513) and get 10k dps extra
and class B also gains the same 13ilvls and got 11k extra.
the difference between the 2 classes is 10% and should be fixed since class B scales 10% better.
In the case of elemental we're a bit f'ed as we mostly lag behind and i don't think we scale 10% less than other classes (we can scale less good, but not that much)
But having a gap increase 10%->20% between 2 specs over 13ilvls is not possible. It would mean that one spec scales nearly 100% better than the other.
