So love the game so far. I am lvl 22 Archanist, its beautiful, love the story and the dungeons. But, I am finding combat boring, I dont get new spells often (every 4 levels) and when I do they are underwhelming. I have been using the same combo for a LONG TIME now. (sick pet, 2 dots, small nukes till dead). Will it start to diversify? When I start to level other classes can I mix and match the spells for some variety?

Thank you for any help you can offer.
