Hmm really nice preview looks like the campaign specific players guides will be a must have if you want more character options, not that I wasn't going to buy it anywho but still
hmm for that dark pact warlock with a standard party thats 4D12 + 4D8 + implement 6 + stat 8, hmmm hmm doesn't look a lot about a 58 damage on average for 40 damage spread out amongst the party, and theres a real possibility of not hitting with the power, I'd say make a +1 to hit for each ally damaged as well to make it nicer

Still more options make me a happy player
On the Critter summoning front I really like this, you can still make an attack, then get a move and an attack from said critter get your weasel running about for flanking bonus'

higher level creatures will be interesting but they will likely remain minions from the text.
And also I quite like the art might make a serperate thread on that though, one point on it the thief guy running away looks like he has an eversmoking bottle esque object in his hands
