I agree with Geno in that those squads based expecting something that they now aren't going to get. It might have been a more effective and backed up the decision if there was a thread stating that the rewards were going to change and that the teams needs some help and ideas.
Regarding the 5k reward Geno suggested, a custom gun and melee skin would be a great replacement in my opinion as well, it supports both types of PvP players and should be rewarded to all 25 members as reaching 5k isn't just a walk in the park, it takes a lot of time, dedication and very coordinated team work to be basing around the clock. It should definitely be rewarded fairly and appropriately.
