Nope, now I don't think it's a waste cause you can get many good ninjas which can be breakthrough/skill trials later on. Yea you can get them with a tons of grinding too but getting him here will just cut the time to make them 4 stars by half for new players.

Asuma WB, Ningendo, Gakido, Jigukodo, Kakashi beheading sword and not to mention HASHIRAMA a godlike barrier and buffs ninja with max bt is better than 3-star Madara founder ninja makes this treasure pretty worth it in my opinion.
