WHM vs. SCH -- What is the basic difference.

[givemeraptors]

Here's a question:

Is the learning curve higher on a SCH? A lot of the time when I get queued with a SCH they almost seem like they are not healing at all and just hanging out occasionally healing but mostly doing dps.. I chalked it up at the time that SCH have a different role to play in the fight, but after reading all of your responses I see that it's not the case..

When I do Trials Roulette I frequently DPS more than heal because I find it fun and engaging (even on Titan!). If everyone is dodging properly I don't have much to do otherwise...
