Zone FB isn't pointless (kinda just skimmed a bit so I'm not saying anyone said it was pointless, just giving my opinion). If you're on PC, you have a bigger view if you don't like to zoom out on a device, potentially runs faster than some of your devices (not definitely) and if it does, you can still kill people who afk with a melee weapon or go do some jobs. But yeah, I do prefer to play on my phone since the controls are a lot better.
