The new gear creates problems with players who are currently still grinding to WH, and still have several BM pieces. They'll essentially be knocked down a tier and be in a tougher spot than fresh 50's who have comms saved up to get the newer stuff. The same thing happened to players when they got rid of the last gear grind and the old Centurion sets.
Starting from 0 WZ comms (traded them all for ranked) I was able to earn enough comms for a BM piece for my Shadow on my Commando in about 4-5 matches + daily. So it would be very possible to have all the WH gear, at the current BM prices, from 0 comms in 2 weeks if you get one piece a day (at most that is 1550 comms). The only people who would have an issue with this are the F2P guys with no weekly pass.
