I have a scholar sitting at near BiS ilvl90 (just missing allagan weapon) and my whm is at ilvl88. I have at least seen every fight in the game even though I still haven't gotten Twintania down (I am not as hardcore as I was when I was younger!)

I tend to main my scholar, just because when I play my whm with a bad scholar I find it annoying. A bad scholar who lets their fairy run around like a chicken with its head cut off, using all cooldowns at the start of combat...not using succor before AoE hits and the like...they are horrible to even watch let alone try to heal with. At least when I am with a bad whm I can semi make up for it with being proactive with everyone not just the tank, which is one strength the scholar has over whm.

However, if coupled with a great scholar who knows what they are doing? I love the white mage. Being able to make sure everything runs well and keep everyone topped off is what a white mage does well. When you have a good white mage with you, a scholar can concentrate on the tank, throw succors/sacred soil as needed and not worry about the rest of the group...period. They have a great synergy that I enjoy quite a lot. When with a bad scholar, I tend to draw aggro on whm and run low on mana...because lets face it when the tank gets down to 1/4 life and 3 of the DPS are also near dead....a scholar cant get them all back up as fast as a whm can.

With that said, I dont favor one over the other in 4 man content. I can just as easily get through any content with either. Regen is "easier" to deal with over the fairy for hectic things like some boss fights. Scholar is better when the fight drags on and on and on cause of mistakes or someone being undergeared and you go through mana like crazy. Whm is better when everything is going smooth and you want to pull half the hallway and AoE it down with a regen on the tank and some Cleric stanced Holy.

It all depends on what you want out of healing, and what situation you find yourself in. Benediction does need fixing with the animation/lag on the hit....and a shorter cooldown to bring it more in line with Lustrate though, I will say that.
