As a caster, I have done the rock toss or the Bow spell to good effect, even with his resists to Sorcery. MLGS with the Godrick talisman and other gear has seemed to be the easiest way to beat both phases.
The cast times and sluggish animations on Incants were brutal compared to Sorcery. Not sure if anything was ever done to address that or if it was considered intentional design to make Incant feel different. You had to research the incants with good casting speed, whereas with Sorcery you had everything fast casting or at least felt viable. Half the incantation school was junk. I saw some good tuning patches but Sorcery is still probably the go-to magic school for a caster play.
