When I was a noob I was wholly devoted to the Light and people found that amazing. Apparently that's considered an endgame and raiding phenomenon. I don't see why since an individual doing quests can certainly benefit from improved/cheaper heals. But that was then.
In my 30-40s I discovered the joy of Battlegrounds. Healing your fellow soldiers in battle is a rewarding experience in and of itself. But there's nothing quite as satisfying as melting the face off some smug warrior who is undoubtably thinking "Pfft! He's just a clothie". So I went down the dark path and gained many honorable kills.
When I had enough of killing I left the Shadow way of life. For a time I considered returning to the Holy tree and again becoming talented in that way. But then I met another Priest, an Elf, with powers much greater than mine, powers I had never seen before. She told me of another path which few understand and fewer follow. Most Priests laugh at the very idea of it.
And so it was that I went down the path of Discipline. This lead me to greater stamina, greater strength of spirit, and higher intellect. I learned to turn my opponent's own strength against them and discovered (much to my delight) how to fashion the Mages' own magical energies into a weapon against them. In short: I had become truly powerful.
And I still get the "Z[wash my mouth][wash my mouth][wash my mouth][wash my mouth]ZORZ!!! GOOD HEALZ!"
