Range matters more for this item than it does for most other items, since times where you'd want to use it are usually times where you can't get too close to the items you want.
So if the Phasing AFG's range is calculated differently from every other item in the game, perhaps that should be clarified in some way?
As it is, it's directly misleading. I trusted the range working the same way as other items so much that i even thought the item i wanted didn't exist, and i bet most players would make similar mistakes.
In addition, a player can't even calculate the true range through anything other than trial and error,
which isn't great when you might be pressed for time retrieving some important part from within a Heavy's sensing range, like in [redacted], one of the biggest reasons to keep the Phasing AFG.
