I do agree, Kel, that all healing classes should not be grouped into categories anymore. I've agreed with that since I first started healing (in the days when I was my guild's main tank healer in SSC/TK, for example).
I took a look again at the talent trees in the current build. I noticed what the largest problem is. Discipline is still too bloated, especially at the top.
-If you spec holy and focus pretty much on healing, you miss one point in Test of Faith, Blessed Resilience, and Twirling Light. Total talent points : 5
-If you spec discipline and focus on healing, you lose one point in Renewed Hope, Attonement, Archangel/Evangelism, Reflective Shield, and Focused Will. Total talent points : 11
This means that discipline has a grand total of 42 possible talent points as opposed to holy's 36.
In contrast, shadow also only has a current total of 36 possible talent points.
So, hopefully some trimming is in order. And maybe one extra tool, since Archangel really doesn't seem all that practical to me (how much time will a healer really spend getting to DPS?).
On a side note, I am also sad that Inner Focus is still gone. I loved IF. I use it for all of my on use trinkets and most especially for channeling Divine Hymn.
P.S.: I would love to make suggestions to Blizzard. Sadly, I will never be picked for beta because my graphics card is poopy.
