I initially set it up because bothbsonarr and radarr were making their own api calls to indexers and I would get some “daily max exceeded” for certain sites. The idea was that if one host made the calls instead of 2, I wouldn’t get rate limited as much.

Now I only have my nzb and pb indexers, the first has no such limits because I pay for it, and the second is only used as a second priority, so I don’t really hit limits anymore.

If you have a bunch of arr services, this is useful. But I only have the two, so I don’t think it’s much work to set indexers up individually.
