Priest spell Renew is overscaling/overhealing

[Voodoomaniac]

What is the bug?
Renew heals to much.

What kind of bug is it? (Quest, Class, Spell, PvE)
Spell

How can you reproduce it?
Create a priest, equip some healing gear, cast renew.

Please describe, in detail, what is suppose to occur when this bug happens:
It heals for what I seem to notice, 90%-100% more than usually.

Please describe, in detail, what happens when it bugs up, and how it's malfunctioning:
When renew is cast it simply heals too much, either as a base spell or due to overscaling. This did not occur yesterday so it must have changed recently.

Evidence providing proof of bug:
I can provide a SS but I already spoke to 5 priests and we all had the same issue.

Can't seem to find the spell power coefficient for it around 2.4.3, only post 4.0.6. But I only ran some very light google searches. If you can find the coefficient for renew, then the math is easy. That is, if more solid proof is needed.

It is 100% (15/15=1)
