A very interesting way to add to these packs to request what sets we desire. It does make obtaining a level set much easier. Will the purchase of these packs be limited to platinum alone?

The only down side to this addition is making players lazy. The traditional way of getting an entire set was to farm for it, or wait for farmers to sell items, merchs to buy sets etc.

With the capacity of purchasing an entire level set it does increase the amount of sets in the PL economy. Farmers will still farm, but pvpers & merchs will most likely purchase an entire set without farming at all.
