OK played a few rounds with it, Quite enjoyable actually.
These weapons fit the JB gametype greatly.
Even the "arenaspoils" addon will give you the right weapons
and the logfile was as clean as it is with JB in a normal match.
Some sreenies:
1: This sniper is the wet dream of every camper, slow but great damage
I just loved camping arround in heights with it
2: Ahh thats where I left my pineapple!
3: Frosbite was Gibbed by knife
Overall a pleasing combination.
