While discussing TBC Mana Management with a friend, it occurred to me that there are new abilities and items in TBC to help the theoretical healerguild.
First let's talk about the new ranks of Judgements and Totems:
Quote:Judgement of Wisdom (Rank 4)
Attacks and spells used against you have a chance of restoring 74 of the attacker's mana.
Mana Spring Totem (Rank 5)
120 Mana
Instant cast
Summons a Mana Spring Totem with 5 health at the feet of the caster for 1 min that restores 12 mana every 2 seconds to group members within 20 yards.
Everyone in the healerguild will have access to melee weapons that auto-attack at 2.0 speed or faster, so you're looking at a regen of 43 MPS, minimum. Alliance druids already use cat auto-attack off JoW (1.0 attack speed ftw!) and I know priests that hunt down 1.2 speed wands for the same reason. 43MPS over 2 minutes is 5160 Mana
Second, a couple of trinkets on thottbot:
Quote:Oculus of the Hidden Eye
Binds when picked up
Unique
Trinket
Requires Level 65
Equip: Increases damage and healing done by magical spells and effects by up to 33.
Use: The next opponent killed within 10 sec that yields experience or honor will restore 900 mana.
Cooldown: 2 min

Power Infused Mushroom
Binds when picked up
Trinket
Equip: Restores 200 mana when you kill a target that gives experience or honor. This effect cannot occur more than once every 10 seconds.

So a potential bonus of 1100 mana on a kill every 2 minutes. With the totems, we're at 6260 Mana over 2 minutes.
And last, let's talk about Vampiric Touch, since healerguild will undoubtedly have no shortage of shadowpriests:
Quote:Vampiric Touch - Rank 1
Requires Level 50
325 Mana 30 yd range
1.5 sec cast
Causes 450 Shadow damage over 15 sec to your target and causes all party members to gain mana equal to 5% of any Shadow spell damage you deal.
Trainable Ranks Listed Below:
Rank 2: 400 Mana, 635 to 640 Damage
Rank 3: 425 Mana, 685 to 690 Damage
How much damage will a shadow priest be doing? Although a dedicated Shadow priest will have plenty of +shadow gear, but I'm going to ignore that as well as the global cooldown just to establish a ballpark baseline:
Shadow Word Pain @70: 1236 over 18 Seconds (69 DPS)
Mindflay @70: 528 over 3 Seconds (176 DPS)
Shadow Word Death @70: 572 every 6 seconds (95 DPS... until the priest runs out of HP)
Approximate damage @70: 340 DPS
Minimum returned mana: ~2042 Mana (17MPS over 2 minutes)
(I've seen calculations on Shadowpriests achieving over 700DPS in TBC, so in spite of my faulty calculations, this is conservative)
The healerguild members will easily hit 8302 mana during a 2 minute fight. They will probably need healing rotations so that some people can regen off Judgement of Wisdom. This analysis also ignores the Shadowfiend, BE Racials, Innervates, and any baseline regen that people have. I think the healerguild's biggest (mana) problem will be mana for buffs and not mana between fights.
