I'm currently playing in a 10 man guild progressing in DS hm. I'm the only player taht can supply a 10% spellpower buff, so currently I feel I have to play demo if we want to progress smoothly. However, I don't really enjoy demonology that much and would prefer to play affliction and destruction. Is the 10% sp buff really worth it, or could I be free to lay what I want?
Tanks- Blood dk and feral tank
healers- holy pally and resto shaman ( our druid and priest heal on some fights )
dps- warlock (me), two hunters( both survival), priest, arms warrior and a combat rogue.
My armory in case it's important: http://eu.battle.net/wow/en/characte.../Drup/advanced
tl;dr Do I need to play demo just to supply the sp buff?
