Kanna Skill Build

It not really it just people are being lazy. Does not take much to alt-tab and match the skills. They can easily just google a guide with the gms names it really isn't that hard to do. Matching things up is something you learn to do at a young age.

Having to search for information outside a guide is arguably a shortcoming of said guide. This particular problem is borderline though, you should be able to get enough information through the actual game to be able to use this guide.
Point is still that the easier the guide is to use, the better it is though.
