I like the sounds, effects, juggling of 2 systems with gauge and sketch and a good deal of deviation at high level between when to Holy and when not to Holy as well as setting up big bursts with Hammer and Moogle. The brush also doubles as a Magic Wand which is really cool.

Probably the most interesting job class to play around with. You'll always be doing something whether it's hardcasting or prepping for big damage.
