You should definitely take a look at the Magus class mod. Without question the most customizable and varied Class I've seen added. It has 5 subclasses that play quite differently, and a whole suite of abilities similar to Eldritch Invocations. Oh and it uses the Wizard spell list and uses TONS of elemental damage types so it is an an absolute gold mine for Class Builds
I played a couple of Blood Hunders: a Dual Wielding Order of the Mutant (hope they'll add it), and a Hand-Crossbow Ghostsalayer. That Radiant weapon was SWEET! Toss in Crosbow expert + Sharpshooter in D&D, and you do SO MUCH damage! So, Yeah. Like this class.
