Actually I would say it's more a pride thing. Look at how long it took for them to change living dead to being a useful invuln despite 9 years of people asking, increasing asylum's radius from hw to Shb after Sacred Soil became the better of the two, or them overlooking Aero 2 potency change back in 6.1. Heck, look at the changes in 6.1 most of those mp changes to help healers at the lower levels were mostly the cost on the offensive spells with the exception of regen meaning it would be more mp efficient to use your atttacks rather than your heals.
