After play already 2 months this game i come to conclusion some player cards need some errata to make game more balanced.
There is my opinion:
1 Gimly should have text : Gimly get 1 attack for each 2 DAMAGE on him. Maybe his threat level lower to 10.
2 Baravur : Target player draw 2 cards. Limited once per turn.
3 Northern Tracker: After Northern tracker commits to the quest chose a location, put 1 progress token on this location.His attack, life and defense level also to strong i think. Maybe he should to be unique????
4 Theres is no limit how many cards you can draw per turn but in he end of the turn every player must discard card until he have 6 cards in his hand.
If you use this errata game is more balanced and become more interesting. Other wise 50 cards expert decks destroy all this core quests easy (mostly in coop games) But even i solo games This 4 cards from above also too powerful.
