Palen,
Here it is how it works for druids:
group heals
-----------
The heal mod caps at 30-33% of the (min-max) value.
example: your Untamed Regeneration goes for 800-1000. Since 33% of 800-1000 is around 266-333, and assuming you have 500 on heal mod, you will be getting 1066-1333. (800-1000 + the 33%). The rest of the heal mod will be wasted since you're capped.
Single target heals
------------------
The heal mod caps at 50% of the (min-max) value.
example: assuming return to the pact does 2000-2500, and assuming you have a 1500 heal mod, you'll be getting 3000-3750. (2000-2500 + 50%). The rest of the heal mod will be wasted since you're capped.
Do note that heal mod only affects the 1st tick of each healing spell...meaning, heals over time (group heals), will only have the 1st tick with the mod...the following ones will be normal.
Of course that you will always be getting the benefict from the heal mod on single target heals, since they only have one tick
- Do note that using base heal increase gear does stacks with heal mods.
- This is the same for spell mod.
Heal crits cap at 100% for heal mod and for dps it varies...check this:
