Hey. So here's my feedback. (Tier 3)
The mission was really fun. The battles were long, tough and very action filled. The level itself also looks good. I got a payout of about 3500 crowns after all 3 floors, which is a respective amount. The enemies were challenging, i had a really great experience in this mission. The level was also as hard as i expected it to be (not too hard and not too easy).
I did 2 tier 3 runs; 1 with a good friend, and another with 2 more players. We really enjoyed the levels.
1 thing that was a bit disturbing: At the 2nd level, there is no party button, so if 1 knight goes to the center, he can ruin everything for the other knights who might have not finished loading or are not ready.
Overall, the mission is really fun, i really enjoyed it and it has a good payout.
