Its pet placement/management that seperates the Bad SCH's from the good.

4 mans? I can cleric stance and DoT up trash while fairy heals.

Boss fights? I can position Eos, use Rouse and activate Whispering Dawn when I want it so everyone in grp recievies Regen. (Demon Wall in AK when Bees spawn helps)

When the group has 4 physical DPS, I can position Selene and use Fey Light and not have her override it with Fey Glow as soon as its cast.

If you dont manage your fairy, you'll never reach your potential.
