Surely the answer is simple (not sure if anyone else has said this) but BW can fix the times in 2mins, by removing caps on comms. Most my char's are tanks/healers, and I barely run FP's as I stick to OPs, and I get almost my entire weeks worth of Ultimate comms from there, so I don't bother with the Weekly FP. Plus the gear reward is awful from FPs so why do them.
Scrap the cap limit, and give a couple of Ultimate comms from running each FP, and people will run them. Otherwise there is no incentive to do FPs, when you can get better gear from OPs.
