I enjoy the feature; it adds to the complexity and unpredictability of fast paced gameplay. What I don't like, however, is that you can still become disoriented if an explosion occurs in a separate room that you are close to. I.e., Even with a wall separating you from the explosion, you can still be dazed.
Dazing is realistic, and I like it. Dazing through walls is not realistic, and I'd like it to go away.
