For Soloing and DPS:
KOS: STR/INT
EOF: Blessing/ Smites
For Being Uber Healer:
KOS: INT/AGI or INT/STA
EOF: Blessing and Cures (for santuary only) or Blessing/ Smites with a couple points in Spurn.
I like the casting haste rather than the heal crit so dropped STA to pick up AGI.
I suppose if you're running COV/ Unrest / MMCC/ MMC or other undead zones then the WIZ line works pretty nice to add to your DPS but it's usefullness stops there imo.
