Really at the end of the day, there are many ways for one to clear wind rag. Some are more efficient than the others. If you do not have the required hime to clear the wrag the easy way, then you opt for a less optimal solution, and so on and so on.

Although the baseline requirement to clear wrag easily is pretty clear to me... Have a respectable fire grid + team, and your wrag farming will be less hellish. If you have to go the harder way because of not having good fire team/top tier fire himes, then it is what it is. Share your wrag to public and hope for the best. It may not be the most efficient solution, but it is probably the only solution you have.
