Yeah, that's what I always imagined for the two Priest specs:
Holy: Great AoE healing, mediocre single healing
Disc: Great single healing, mediocre AoE healing
Yet for some reason, Blizzard seems to want to homogenize the two specs, giving Disc buffs to PoH and giving Holy buffs to their single target via Chakra. It's just...why? They're two different specs, why struggle so much to homogenize them?
