I have a few questions about current lvl 70 gear. With Wrath coming out in a few days, most of my gear, both main sets, Tank and DPS has all these gem slots filled for their respected task.
1) Should I re-gem them to help me run through Northrend to lvl 80 or keep what I have.

exam: The Onslaught Chestguard; which is slotted with (3) 15" Stam be left alone or fill the slots with +hit and or +crit. (This and other T-6 gear looks to be good to keep until around lvl 75 - 77.
2) How important will Defense be during this stage to lvl 80?
3) Agility??? I notice none of the gear for Warriors has agility any longer. Has this stat become useless for Warriors???
4) Any comment on Enchants, especially for weapons??
ie: Mongoose / Executioner / Potency
Which of these will be best until lvl 80?
