My last character isn't turning out to be a great damage dealer; should I make him a support character (possibly with time magic) or a pure combat character?

Time magic is quite powerful, and even just the Battle Resurrection spell is worth it. Considering the number of damage dealers we have in our party (my character, Neyra, Sive, Arandor, Mirastir, and Nysan's bodyguards), including those with unusual damage types (light from Sive and Neyra, darkness from Arandor, air from Neyra and me (water and fire will come later)), a support role seems like a more useful option.

I mean, the origin doesn't really lend itself to magic.

That's okay. It's not the best option, but a rogue with some magic skills wouldn't hurt, even if it's just for dodge and accuracy. Although, considering Revan's words, the other origin-based skill branches don't synergize well with magic.

And Ples can also deal elemental damage, and he seems to be unmatched in that regard.

Well, yeah.
Due to the investment in the Philosopher skill, his full potential won't be realized immediately. Although, high intelligence should speed up this process.
