I'm genuinely curious about the logic involved in this. I saw someone in zone chat ask for a bite, and the only person available to do it was busy but said they'd do it but since it was interrupting them and out of their way they were asking 10k, to which the asker agreed. Immediately, first one and then a bunch of people jumped on the would-be biter, calling them all sorts of names and being generally hostile and angry that they would dare charge for a bite and insisting that bites should always be free. I've seen this sort of conversation many times over the past year, and no one ever answers me when I ask in zone chat: Why is it different to ask for gold for a bite than it is to ask for gold for Skyreach runs, or mats, or something that you stumbled over in a treasure chest?
I know people who bought the bite in the crown store, way back. I also know people who farmed *hard* for the special spawns to earn their bite the hard way out in the wild and are very proud of that accomplishment. So why is this worthless compared to an accidental find, or some time spent picking up a few nodes, or running content with someone to help them earn xp? The bitee is basically asking to have an entire skill line shared with them. Why is this worth less than someone's higher CP level in Skyreach, or someone's luck with a chest?
(Note--within guilds I see a lot of bites given back and forth to guildies, but I also see a lot of items and mats and gold and carries given freely, too, so that's aside from this "random request in zone" thing.)
