-NPCs should speak! I remember the days of diablo 2 and everquest 2, and the NPC speech really adds to the game experience. Hearing Prince Rurik shout those battle taunts would really contribute to the game play. Also, when you get a quest, the NPC should speak as well. For those of you who wouldn't want to hear it there could simply be an option to turn off NPC speech.
-Although the cinematic sequences are well done, they are really degraded by the fact that the mouths do not move! I would be very content with simple mouth movement, but none feels weird.
-This may be a little geared to one class, but i noticed that Necromancer bone horrors die extrememly fast! The necros on the team can never get an "army" raised by traditional Necros (thinking of Diablo 2). I dont know about the other necro minions, but the horrors seem to die before we ever encounter the next group of enemies

Anyway heres my two cents, tell me what ya think! See ya in game. (my name in game is Zakarums Wrath)
