Gonna try to adress all of this, but its a little disorganized; sorry.
+healing gloves are *very* viable; mana efficiency, survivability, and healing output are all far more reliant upon spellpower than stamina and intellect.
However, ideally you would want the mail +13 healing gloves; Pillager's Gloves of Healing, iirc.
Again, Phalanx Leggings of Healing is what I use; I have a 9/9 eagle, and they rarely see use (FCing).
[item]Acidic Walkers[/item] vs [item]Spidersilk Boots[/item] seems fairly obvious to me; As you're using cloth in that spot, you're declaring you dont care about armor, so it boils down to 4 int versus 4 stamina and 3 spellpower. Obviously the latter is preferrable.
Once you pass the ~1500 mana with a sp weapon equipped, any more is better itemized towards stamina and spellpower.
+18 stamina to your Basalt Buckler to start fights, then switch to a +7 healing shield with vitality when injured. Use the Marbled Buckler quest to pick up the heavily armor belt for an anti-rogue/hunter or Fcing set.
Gnomebot Operating Boots are my boots of choice while healing, and the AB boots with +7 stam when FCing or when I feel I need the armor.
@ OP; as mentioned above, you have far too much mana, and not really enough spellpower. Some potential changes for you:
*+21 sp goggles. Debateable, I have both, and the Wisperwind rarely gets used.
*River Pride Choker. Interestingly enough, I've never picked one of these up, but it seems to be best in slot. The same stat points as a 4/5 eagle even (what I've been hunting for) and some extra str to increase how much your blocks stop.
*You have the BoA weapon, why not get the Wintergrasp Shoulders? If not, [item]Death Speaker Mantle[/item] is the next best option.
*While 5 resistances is acceptable, I find more use for +10 shadow resist. Stacked with shadow resist aura, you can get some nice shadow mitigation. I carry around +shadow resist rings, and they find a good amount of use.
*+150 hp vs +6 stats. Debatable; technically 6 stats is 'worth' more, but you already have enough mana. Try out +6 mp5 if you feel like you dont really need extra hp; but with the +int talent it takes somewhere close to two minutes of non-drinking combat to get the same mana returns from mp5 as +6 int.
*With the changes to the +healing enchants in late BC (making +15 sp to bracers available to 34 and below items), Gallan Cuffs is nowhere near the best option. The remaining options, in my order of preference:
[item]Spidertank Oilrag[/item], [item]Renegade Bracers[/item] of Healing (+9 sp), [item]Emissary Cuffs[/item] of the Eagle (5/6), [item]Renegade Bracers[/item] of the Eagle (5/5). Your enchant of choice is +15 spellpower, from AD rep.
*Alternately, a [item]Renegade Bracers[/item] of stamina with +9 stamina enchanted can be used, if you're having trouble with living long enough to LoS hunters.
*While resilent are a good choice, I prefer the armor from a leather or mail 'Of Healing' piece.
*[item]Moss Cinch[/item] really is a bad option. If you feel the need for additional stats, a [item]Girdle of the Blindwatcher[/item] is a better option; Otherwise, go with a +13 sp [item]Ghostwalker belt[/item] or a +12 mail [Pillager's Girdle[/item] of Healing.
*Abom Leggings are no longer able to be obtained. Im unfortunate to have not bothered to grab them during the last event - "No way they'll take away leg kits after all this time!"
*The next best leggings are a 9/9 Eagle or a +16 sp. I prefer the SP myself.
*Boots, as mentioned above, are any of Spidersilk, Gnombot, or the AB boots
*I would HIGHLY recommend getting run speed to your boots. Rogues will have it from thier AB boots, and with good positioning and runspeed yourself you can cleanse crippling, make a sharp turn, and run from them forever. Don't forget JoJ when the sprint!
*[item]Deadman's Hand[/item] is best in slot, no doubt about it. Get a Charged gear of Stamina to pair with it when FCing, and consider [item]Seal of Argas[/item] for a pure healing set.
*I'm a huge fan of the [item]Gnomish Net-o-Matic Projector[/item] from engineering. I swap to a sp trinket or insignia only once the net is used
*
Start fights with a +intellect weapon. This is how you can afford to stack stamina and spellpower instead of int on your other pieces of gear. Ideally use Skullbreaker with +30 int, but a Zealot Blade or the other BoA Mace (use the Pve one with +int and the PvP one with +30 sp) will work quite nicely as well. I'm currently using a Zealot with 22 int and a SBK with +43 sp, because my BoA mace is on my priest
*Finally, a +7 sp shield with +4 mp5 is a valuable addition to your healing arsenal.
-Of note (Spellsurge)
You shouldn't be OOMing often enough to see any need for this. Consider that by switching to a Spellsurge mace, you will lose roughly 200 healing done while waiting for it to proc, so to make that up you really are only getting about 75 mana from it. Also, you healing/second will drop.
I'm really considering writing a guide; having to explain this over and over is getting to me. Maybe next week
