I'm mostly surprised by the final tier of spells. I was kind of expecting it to be the second-to-last tier, especially after seeing how you can obtain a couple of them in act 1. Then again half of the pictures are of late game DOS1 spells, so their DOS2 equivalents are bound to be strong as hell. It seems like many (all four elements, huntsman, blood storm, maybe the summoning skill) of the final tier spells are going to be medium-sized AOE abilities that deal damage.
Looks interesting. From what I see only summoner can summon creatures. Even necromancer don't get some "rise undead" skill.
There's at very least a 'summon bone widow' skill for the Necromancy skill tree. In one of the Kickstarter videos they briefly hover over it.
