The main reason I haven't flown premium LY until now has been for two reasons: (i) the hard product, and (ii) the mileage program.
They're fixing the former (at least to be in line with competition), but they haven't (and I suspect won't) fix the latter. As such, I'm still not going to fly them premium, unless I can book them using BP 50% in the next year.
All that said, I won't bash a product until I've flown it.
