STRICTLY my opinion, but if a new currency is involved for only the winners, I'm pretty sure that currency can be invested into something really special, such as possibly the things required for Awakened weapons. Again, this is my opinion. But right now in light of all other ideas in the forums that I've seen, these are the only plausible items I can think of that the new currency could be worth for.
The only idea that could defeat this for me is perhaps that since Awakened Weapons are for lvl 65s then some level 30s and 40s may earn enough by the time they hit cap to be able to get their weapons faster.
Again, this is all opinion. ><
And thank you Sighborg for giving us the heads-up!
