Hello,
I did some research and found a wowwiki article back in times.
It's from august 2006.
Just a quote:
Rate at which health points regenerate.
No regeneration occurs in combat, except for trolls.
There is 1 tick of regeneration every 2 seconds.
Health Regeneration is increased while sitting.
Its value depends on class and spirit:
Druid:
Spirit * 0.09 + 6.5
Hunter:
Spirit * 0.25 + ?
Mage:
Spirit * 0.10 + ?
Paladin:
Spirit * 0.25 + ?
Priest:
Spirit * 0.10 + ?
Rogue:
Spirit * 0.50 + 2 Confirmed at level 60 patch 1.09
Shaman:
Spirit * 0.11 + ?
Warlock:
Spirit * 0.07 + 6
Warrior:
Spirit * 0.80 + ?
(Probably each regen rate should have a constant added.)
Trolls regenerate 110% of this amount while out of combat, and 10% of this amount while in combat.
In the revision of february 2007 of this article health regen is increased by 33 % while sitting.
The constant (the ? in my quote) for shamans is 7 and for warriors it is 6.
There is no health regen durin fight through spirt except for trolls. They get just the 10%.
