So here is mine
How will you spec?
It was actually a little difficult to decide what I wanted, between Serendipity, Test of Faith, or filling out Empowered Renew. I'm still not sure which one is better.
I decided against Empowered Renew. For me, it would be mostly wasted. My renew is just meant as a buffer, most of the time I put it on the tanks, while the 15% increase in healing would be fine, the instant heal would be wasted since they are usually full health when I hit them with renew. So that right there cuts the value of the talent in half, plus the fact that I don't really rely on my renew as a healing spell, so much as a buffer spell(I leave the HoTs to the druid I run with). But I did put 1 point in it just for those times when I don't feel like healing a DPS I drop a renew on them, the instant heal plus the HoT should be sufficient to keep them content and alive.
Test of Faith vs. Serendipity was the real challenge. The 12% boost is a much more enticing boost than the old 6%, combined with the ability to target other parties in the raid with PoH, I see serious potential with this spell. On the other hand I see serendipity constantly being active on my buff bar(since I do cast flash and binding quite often), and a 60% reduced casting time on either GH or PoH at 3 stacks, making PoH a 1.2 second cast, I just couldn't pass it up.
Quick question for any number cruncher, that I'm curious about. As far as the Hot is concerned, which is better, increase the amount healed by renew by 5%, or your renew gaining an additional 5% of your bonus healing affect. My math is saying the 5% increase in healing is better. Renew has a 188% spell power coefficient. Meaning if you have 2k SP, your renew should tick for 1032, or heal for a total of 5160 ([{1.88*2000}+1400]/5). Now with 5% increase in healing, that would be 5418 or 1083 per tick. Whereas 5% gain of healing affect ([{1.93*2000}+1400]/5) would be 5260 or 1052 per tick. Am I doing my math wrong in how renew would be affected by either talent?
PS. I am assuming the Empowered Renew instant heal can crit, since the new Holy Concentration talent includes renew as a triggering spell.
