Nice. I have to try summoning next it seems hilarious. Yeah I never really tried doing any huge min-maxing, I might start a new game now that I finished and do a lone wolf or completely different comp. Mage was so fun, I'll definitely still use it.
Most of the game I would blow everything up with my Pyro/Geo on the first turn (teleport enemies closer+explosive mine+impalement first turn one-shots or nearly kills almost anything from high ground, and also crits), and never really needed any other element until later(geo is great because poison and earth are two different resists). Always took high ground when I could to start of course. Even if they were immune to one, I still had more than enough from the other element to use. And by the time I ran into enemies that were earth+fire resistant, I had stocked up on some Air.
I don't think there is ever a need for more than 3 different elements since the enemies normally are immune to only 2 at most? I didn't like hydro much either.
Also pro-tip to anyone who hasn't noticed this: An optimal way for elemental damage is to put only the necessary points in the element to use the skills. The rest should go into polymorph>intelligence to give ALL your elements 5%. Then huntsman for overall high ground, and THEN put points into the individual elements when you're maxed in those.
