It'd be great for us to be able to see which regions have the worst ping when planning routes. I understand lag is inevitable, and that the performance of the game is something you guys are working on, but in the meantime- at least allowing us to be able to work around it would be amazing. It could help save time, frustration, and hours of trying to find the mount you just lost at sea by just letting us plot a good course. It'd even be good for the roleplay community inside of Atlas, could explain it away as 'Choppy seas' or a bad storm of some sort. At least in the global PVE server, right now the equivalent is basically 'Avoid all lawless regions', which sucks because at least some of them are OK-ish.
