My main beef with the sniffer apps is that they're really crossing into the "blatant cheating" territory by giving their users information they were never meant to know that also gives them a huge advantage over other players in a free-for-all environment where people aren't wanting to share hunts.

It's not too bad in small maps like Upper La Noscea that can be covered quickly or wide open ones where you can easily spot the S ranks from afar like Western La Noscea, but for huge zones like East Shroud and Coerthas Central Highlands that are big and filled with clutter that makes the S ranks difficult to spot, it can be hellish.
