Personaly this build suits my dwarf priest beastly(i find priest main role to dispel both offensive as deffensive, shield friendly targets, throw renew, mb few heals. Pala healing is way more effective on wsg then priests)

I prefer offensive style of play, silance must be for me for few reasons:
Can avoid cc from mage.
Can avoid huge burst on me or fc
Offensive play.
And other talents:
blackout - very good skill, only talent that allows somehow kite enemys spaming r1 swp (RNG!)(priest lacks cc/kite abilities, i don't speak about engineering but basic class stuff)
mind flay - slow. nothing to add, can be a savior for fc if holy tree is locked.
Shadow focus - fear resists. Sorrie priest lack of hit.
shadow weaving - +5 debuffs to dispell for enemy class. swp rank 1 - ~25 mana dispel ~200 mana
Holy nova - against enemy rogs. instant heal in nuke situtations.
Idk why to go full disci, when disci tbh doesn't have anything that support fight beside 3 min PI. Although disci have less mana issues, still all mana issues i cover with combat mana pots spam + zg staff with 20 spirit enchant
