Let 2 SCH shields stack with diminishing returns

[Squa]

WHM isn't a better healer. SCHs can work really well together just as 2 WHMs can but they need more communication. When I am with a SCH I always make sure we have a Whispering Dawn and Fey Illumination rotation. Also, if the fight as phases (most fights do) I will work it out that during such and such phase I will do shielding and the other will just spam Physick so we don't waste MP. Because my MP will run out more we then switch for a phase and all I do is Physick and my MP recovers. I would actually say that 2SCHs is better than 2WHMs given that the two know how to work together. It just so happens that it is rare to have 2 of us that can work well. I do prefer having a WHM buddy though. ^^

SCH has extremely weak AOE healing. THey can heal fine except any fight with large aoe damage. WHM has amazing aoe healing, and also can single target heal great with regen/cure/free cure ii. A SCH helps a WHM do his job well (not the other way around)
