So, there is not update enhancements tree in this patch.
SSG just add some domain. You can select only one domain at 2nd cleric level. I really hope for new feat that allow you get 2nd domain (but this will never happen).
So what about current domain:
Spellpower:
Air, Earth, Fire: allow you use elemental spell power for light. (I really want to test spell crit and spell crit multiplier for this but I don't have enough time. RAW says only about spell power.) And one interesting things, this domain power don't work with utterdark (you always use light spellpower for blast, but this things work with pact and additional light damage).
Spells:
Death: cooldown for Destruction 12 sec (20 mana). I think with 6 sec it would be more interesting.
Luck: displacement at 5 lvl, and no auto fail save at 1 (So before I drop DDO almost 40% of my save roll were 1...)
Trickery: Charm Monster mass and dc for this... (but i really think that wizard will be more efficient for this). Also contain CHA boost.
Boost:
Knowledge: interesting for boost dc for wizards and Know the Angles (some will get boost for damage and attack)
Magic: spellpower boost for party.
War: I think this is the most interesting domain (ML/RP, Tactic DC, holy sword)... But you need only 14 cleric, because warpriest tree is useless compare to kensai...
IMHO:
So this domains above the average. There is only one interesting domain for me: War (if SSG update warpriest that would be great). If spell crit profile and utterdark will work with Earth/Fire domain that would be great too.
Not listed domains are useless.
