I agree with DE in the sense that I much prefer this kind of arc compared to those filled with meaningless fights. We have had plenty of those, and no doubt will have also in the future, if the fillers won't stop. It's not like in the reality the bad guys would always just seek you out and everything was solved by kicking their asses. This arc is even brilliant compared to most of the fillers arcs, because little seems evident or clear right away. I'm not bothered at all that there has been little hard action.
