The Directives themselves seemed a bit of work and time-intensive to complete on the PTS, though they'll probably work in the live server given a realistic timeframe to complete them. I did spend a lot of time in my first PTS adventure just screwing around with builds I wouldn't be able to in the live server.
I really enjoy the updated sounds. The bigger the variety in gun, ricochet and penetration noises the more thankful my ears are since it makes the game more immersive and fun. Oh, and more diverse horns would also be giddily accepted.
