I am/was a scholar, and whenever I see the other healer is a scholar, I kinda get disappointed. These groups always have trouble. Two white mages will never have this same degree of useless overlap. On a scale of 1 to 10 if SCH+WHM is a 10 and SCH+SCH is 1, then WHM+WHM is probably a 8 or 9.

Its why I ended up making one. You can argue about which healer is better and get 100 different opinions, but when it comes to stacking, there really is no "silver lining" for the scholar. Two white mages can get the job done and barely even notice what they would be missing by having a scholar. Two scholars are too well aware of what they are missing when they both start pitifully spamming succor after the big AE damage. And no, the succor they casted before the AE (whatever was left of it) doesn't do much to help either. And yes, the faery HoT would be nice, but has no upfront healing which is so desperately needed when the whole party is sitting at 10-20% health.
