Back in the day when Brethren of Frostmourne was around we had the pally named Icekiller (some how became the Paladin class lead even though every other paladin was a better player). In MC fighting one of the bosses his idea was for all the pallies to blow LoH at the beginning of the fight to allow the other healers to save mana. This is when LoH drained 100% of the paladins mana and regen was !@#$ty at the time.
I remembered this when I was thinking about the old days and the arguments Nomak would have with the one lolworthy paladin that would always argue with him.
