Loving this game so much but man, the bugs are bad. Weird text string errors when you try to take some feats, currently spells not showing up when you level a Sorc (devs are apparently working on a fix for this), Amiri flat-out just got removed from my party in a bug during the Barbarian war quest (she just sat in camp saying "let me know when you're ready to leave" - when you leave, she went missing) - and now, for a totally game breaking bug, Armag's Tomb simply isn't showing up for me no matter what Kingdom events I complete. Supposedly from Steam discussions a lot of people are experiencing this bug, which makes it impossible to complete chapter 4.
I think I'll come back to this game in a month or so when things are a bit more... uh, polished. It's more fun than I've had from a game since Baldur's Gate (the D&D/Pathfinder ruleset in a game just makes me swoon!) - but it's also more frustration than I've had in a game since I can't recall.
My tip for the game is that Heavy Maces are a really good weapon choice to specialize in, and Crusader clerics with the animal domain make for a really tough main character when built right. They can be front-line melee characters with a tower shield like I made my main, or they can be excellent archers when taking the right feats.
