One thing I did notice last might was while playing a round of TDM spawns weren't shifting. The way the system works for TDM there are 4 spawn zones each with four fixed spawn points. The zones rotate periodically during the game to make it feel random. Last night my entire team kept spawning on the same spawn point hte entire game. It was the first time I have ever seen a TDM game get spawn locked. I'm sure this is something that can be easilly fixed.
Overall the DLC is amazing. The crossbow has a nice balance to it, very situational and not over powered at all. Map design is great and just a lot of fun. Good job on this one DICE. Now fix the TDM spawns.
