The game is so easy that it basically doesn't matter how you build your characters unless they are just plain terrible. Min/maxing is fun, but hardly even remotely necessary, especially for the second half. So just do whatever you want.
That said, I played a wayfarer mostly focused on Witchcraft and Expert Marksman, with glass cannon. I tended to use spells for buffs, utility, debuffs, and summons ,and I used the bow for damage. There's plenty of non-damage, mostly low level and AP, spells that don't really get much better with more intelligence. So you can throw most points in dex, con, and perception and 3 or 4 in int and you'll be more useful than a plain archer overall. With slows (midnight oil is incredible for that), bully, and oath of desecration, you'll be able to do more damage than a regular archer as well. SUre, you could have another mage do that, or you could have two wayfarers and do more damage.
