About regular mags

Did Sega said anything about what do our regular mag do instead of stat boosting in NGS? or if we still have to feed them EVERY time?

So far it's known that mags give the player visual signs when nearby certain locations, like towers. Other than that, dunno if they'll do anything else. When it comes to feeding, instead of feeding personal mags, seems like we'll be feeding a huge region mag, one that every player can feed, but I dunno about the specifics.
