To be honest SCH is super useful. Their AOE/barrier attracts less hate/enmity along with their single heals vs WHM. Also their damage barrier drop is super useful in Garuda Hard Primal and I guess easy. [When she jumps up and destroys the rocks your team takes hella damage ^^] Regardless, my team that does Titan hard ALWAYS takes at least 1 SCH. As crazy as I might be my next relic I am going for the SCH book. SCH balances out WHM now so they don't really/shouldn't be spamming heals and collecting all the hate. SCH can spam. Whm can't.
