A lot of us know the frustration of the levelling FP''s not popping. I hate KDY and for that mater all TFP's. But even if all the people that are in KDY were in the FP queue, sadly they still wouldn't pop. No tanks and healers queuing is a problem. BW gave everyone a pop with KDY. BW also gave us the KDY Academy Graduates also.
Most of us that have low level toons feel the pain, but I don't believe limiting KDY will fix that.
I know I said that I hate TFP's, but it would be nice to get these story FP"s done. Maybe that's a way around it. The problem with TFP's is that they require no class understanding, no role understanding, no group awareness and for the most part no skill. You learn this knowledge and skills through group content like FP's and heroics. We would end up with more KDY Grads. Sad but true:(
Maybe increase XP, loot and social points (better rewards for social points) for FP's to give more incentive to queue. More patience would help. Chances are that 2 or 3 people in the FP group might be learning a new class/roll.
