Game Mechanics: Group heal agro way too high

[Treats]

Could it be that Group heals are giving the amount of Hate right now equal to the spell's maximum instead of the actual healed value?

Ex:

Cast Word of Restoration on Group (10k group heal)

Heals Player A for 3000
Heals Player B for 2000
Heals Player C for 1000
Heals Player D for 2000
Heals Player E for 1000
Heals Player F for 3000

Generates 60,000 Hate? Instead of 12,000.

No idea without knowing which heal/threat mechanic is in use right now.
