SCH gets naturally dispel and Break also, thus few spells naturally.

RDM enfeebs tend to be better but blu can do just about all the enfeebs we can do while doing dmg at the same time. As for defensive, naturally w/o looking at subs blu has 2 versions of blink ( one being 7 shadows), pdt, lower quality stoneskin and a few others spells while also can set traits to help it defensively.
