I just want to make sure everyone who did not attend the last raid or does not already know understands the big mana change. Intellect is no longer giving mana. Your mana is instead being based on your level. This puts spirit in a much higher position than previously. Items that would normally be almost wrote off for their high spirit at the cost of intellect have now become arguably best in slot. For instance,
Dalewind Trousers - Item - World of Warcraft among priests and resto druids are going to be a much greater item than before(pallies and spell using shamans should still use green dragonscale for the set bonus).
I'll just list a few more big items I saw that have recently rose in viability, arguably to the point of Bis:
Eye of Adaegus - Item - World of Warcraft
Obsidian-Flecked Cape - Item - World of Warcraft is taking the lead against
Caretaker's Cape - Item - World of Warcraft
Lei of Lilies - Item - World of Warcraft is now a clear bis item if it wasn't already, the dragon's eye is still fine if you have it
Robes of Insight - Item - World of Warcraft is the best thing if you didn't get Alanna's embrace fast enough (for clothies and leather users)
Sandals of the Insurgent - Item - World of Warcraft Are decent if you feel like not using rocket boots for some odd reason. WARNING they are leather.
Gloves of the Atal'ai Prophet - Item - World of Warcraft Are now the best priest gloves versus Bloodfire talons
Stonerender Gauntlets - Item - World of Warcraft These are pretty awesome, but not in my mind worth losing green dragonscale.
Cogspinner Goggles - Item - World of Warcraft Cogspinner goggles of the elder, if they didn't before, blow all other head slots out of the water imo. Another leather warning here.
Scepter of the Unholy - Item - World of Warcraft could challenge the heirloom mace due to it's combination of spirit and the 30 int enchant
Mountainside Buckler - Item - World of Warcraft is now taking the best in slot vote for me, crest of supremacy is still viable however. Plus it looks great with the green dragonsacle mail.
Living Shoulders - Item - World of Warcraft these now are decidedly better than ironfeather shoulders.
Flamescarred Girdle - Item - World of Warcraft this will be replacing my thuzadin sash asap. Leather warning.
Dryad's wrists, the pvp bracers, will stay on my list even though they are inferior in spirit. The int is too good.
In terms of trinkets for non-gnomes, double mindtap talisman is now pretty nice. I'll keep my power of the high chief however. Just remember that, as new items and things are being added and others disappear from the loot tables, intellect is still important. Don't get rid of your noise machines for a mindtap or something silly just because spirit is getting a higher place on the totem pole. And for the love of god don't use something like stockade pauldrons in your healing set for the spirit.
