sp_blitzindex Index Evaluation Results
That one is just an FYI and not something that you should take action on. Some of the rows returned will be FYI-type things, some will be things that you should look into more, some will be things that you should take action on. Like I ignore the "addicted to strings" and "addicted to nulls" rows. Those are just FYIs. I take action on the missing indexes section, though not all of them, depends on the details.
