Makes sense to me, if you were the type of person that was planning on doing all the Avatar Prime fights mutiple times, to take the belts and use towards your next fight. Wind Belt has +20 Earth, thus making it a very nice item to fight Titan the next round. As well as fighting Titan on Windsday. Down side.... it looks like a ton of dedicated work. Best scenario is to have a static group of friends that will work on this plan of action over time. Something I may look into in the near future. lol
- Use each "Elemental Belt" towards the next Avatar Prime that corresponds to the elemental defense boost etc...
