Hello there,
With more and more ulduar upgrades I find myself in quite different position comparing to naxx times- I'm slightly overcapped with both hit and expertise, no gems or enchants to replace, there I remembered icewalker- stat wise it really gives the highest for any dpser I guess, but after spell hit cap reached- "hit" part on icewalker loses quite a bit of its value, so now remembering [item=28279] and tbc movement speed increase benifits (there was a whole post in EJ calculating it) im doubting, should I get cat's swiftness? + for most of Naxx fights you wouldn't have to move that much or even better- had luxury of unholy aura (pre 3.1), where in ulduar you get to move way more while fighting.
There are options like 32ap,16agi boot enchants- but i think icewalker is still more valuable statwise, there is 15stam minor speed increase enchant also- but dps wise 6agi>15stam.
The reason im digging is that its not mentioned in FAQ(or I'm so tired not to notice it couple of mins ago while reading it for like 10th time), so would it be right to claim that [item=28279] best high end raiding enchant for us there is?
