So, doesn’t this kind of defeat the whole purpose of reforging?
Now you can keep banking your XP to keep playing in high level areas and escalations until you have enough to reforge it back to 20. Rinse and repeat? Also, these higher level areas give more XP so reforging becomes faster.
Why not just scrape the whole reforge idea, and put in “Aetherheart XP” or something. Use weapon mastery for empowerment requirements. This will give a good purpose for the masteries. Heck, I’d scrape the empowerments, and re-think the rewards. Hiding power upgrades for ALL weapons behind the “play X weapon wall” is bad.
