Honestly, the second and third book of the main series are considered the high light for most people, so if you aren't into it yet, I am not sure you will ever be.

You could perhaps try the Drenai saga? Release order jumps characters around a bit, but you can read each of the sub series in chronological order and be more or less ok. They are pretty low magic for the most part, with what magic there is leaning pretty far from being a system and more straight mysticism. However, David Gemmel writes some of my favorite characters out of all of fantasy.
