If you want the Azure Water Strider mount, maybe because you’ve heard that the Broken Isles has lots of ponds and streams, you’ll need to get Exalted with the Anglers. I tried to read the guide on WowHead, and got more confused the more I read. It’s a cute, but pretty much useless treatise on the glory of fishing rather than a guide about what to do to get the mount.
Well it’s not that hard to get started from zero in fishing to making progress toward the mount. The guide makes it sound like you need to go back to the starting areas and level your fishing, but you don’t. I started from Fishing = 1 next to Nat and with the basic rod. You don’t need to level your fishing first.
