Realistically, the SCH complaint is that due to WHM having flat out amazing aoe heals and SCH having very weak aoe heals. (Succor heals for about 360 in full DL with relic +1 for any WHM who don't know.) On aoe heavy encounters groups can take Whm/Whm, or Whm/Sch, or even solo Whm (TitanHM) but not Sch/Sch (Not that this isn't possible, just very very inefficient.) Sch is preventive healing that shields for stronger aoe heals to fill them up: two Whm can fill people up with ease while tank healing, while two Sch have to work really hard to do the same thing. Sch just doesnt have the numbers to bring people up without multiple casts for the same healing one Whm aoe can heal. Shields just don't equal healing when you need to bring people up after huge aoe hits.
Also since someone is going to say it, Eos aoe HoT has a long CD, small aoe, and depends on placement, careful management of obey (tanks pulling, better pop my strongest aoe! -every Eos ever.) and the luck of hoping it doesn't get hit by stupid things and die.
Last note, Whm doesnt need a nerf, Sch just needs a slight buff. Anyone complaining about who can heal a WP speedrun better should go talk to the poor melee DPS who never see them.
