I don't think it's working as effectively as they might have assumed it would.

It looks to me like the xp/cp bonus is slightly better than straight up double xp/cp campaigns *if* you're killing VT's and up and keeping chains on them. Which sensibly means that 90% of people would actually have been better off with a straight up double xp/cp campaign that we've got used to.
I'm not sitting there getting mauled to pieces on my 200 job point BLU fighting the stuff in the new zones for double the capacity points of something decent challenge in Adoulin that I can kill in 3 seconds flat.
