i find this class to be quite refreshing and reasonably balanced. only issues i see are the crows base speed is kind of insane with 8 speed at level 0, his camp skills are way too strong for their point cost, and his self heal shouldn't have any negatives at all.

the houndmaster, leper, hellion, and abominations self heals all have no negative effects. the way the crow's self heal works is just unprecedented and an overnerf/overbalance. what makes it worse is that the stress and blight chance go up as you level the heal making it less and less worth it as you level it up. on top of all this at level 5 it only heals for 7-10 while the houndmaster heals himself for 10, the leper heals himself for 12, and the abomination heals himself for 10. all of those characters HAVE NO NEGATIVES associated with their heal. hell, the leper and aboms have extra benefits on top of a stupid high heal. the hellion only heals for 5 but buffs damage and cures blight/bleed. in all seriousness it should either have no negatives and heal for 10 or a lower heal and an added benefit. one more thing i'd like to point out about self healing in general is that the abom, houndmaster, and leper self heals all DOUBLE in total healing (100% increase) by level 5 while the crows only increases by ~40%

as for camp skills i'd nerf the speed and dodge one to 3 speed 15 dodge (or 2). damage and accuracy i think the damage buff is fine at 20 but i'd put the acc to 5 or 10. if you keep it at 10 i would add some sort of debuff like lowered resistances/speed/stress penalty. the camp skills are just way too insane for only 3 points.

other than this though i think the base damage is just right, the mark synergy is nice, and the "blight hound's harry" is a cool and unique skill that makes this class different.
