Having just had my first try with a skyscale in the lws4 mission I have to say it was not fun at all. in the start I had to collect 10 volatile magics, problem was I wasn't high enough at the start t reach them, and then I couldn't even get back on the ledge I jumped from. ended up go lower and lower trying to find another ledge, but nothing till the sea at the bottom and then no way back up.Once I got back I spent a lot of time trying to get used to it, but just felt clunky and a huge letdown of the expectations I had, which weren't that high to start with because I knew it couldn't really fly. the next mission I had to take a skyscale halfway round the island to collect blood. I think it put my blood pressure well above the danger zone ;-) I basically walked most of the way on it, avoiding any combat, because if I got off it disappeared since it was only borrowed. as far as usefulness I rank it only slightly higher than a high vault springer and advanced gliding and a damn sight more annoying to use giving it real flying would make it worth the hassle of getting. An easy way to stop people from skipping new content is to grant a flying stamina buff for each zone you have 100% completion on. not to mention you actually have to have a skyscale in the first place, it's not like brand new players are going to be zooming around skipping everything and complaining there's nothing to do. There's a large amount of game playing and effort to even get the mount. Make full flying a top tier mastery and require 100% in a zone to use it. This gives the best of both worlds, you cant skip new content/zones until you have fully experienced the entire zone and once you have fully enjoyed all the content you can fly over it next time if you wish.
