I have 4 heal buttons that have worked so far. 1 heal tank button on all my rets. 1 FOL urself button, 1 HL urself. and 1 button that , 1 button that heals 2 of the rets while the other 2 dps.
My strategy for Novos when starting out in crap gear is start the fight behind him against teh wall using Seal of wisdom. Wisdom lets you keep your mana up and the mobs dont take long to kill.. may need 1 round of healing. Let things run to you. After you kill the 4th Summoner or whatever and Novos shield drops.
Then switch to SOV/C and stand on the corner of the square that Novos is standing on. DPS boss.. When he casts Blizzard run thru him to the other corner. Turn around repeat. His blizzard is stationary once he starts casting so really only 1 pally should get hit by blizzard as your tank runs thru Novos. heal when needed or switch to Wisdom if mana gets low. He was pretty easy when I did this. He's really not that hard if you take his fight slow. Once you get more geared he barely has time to cast more than 2 blizzards before he is dead.
