How come all the builds from the previous skill trees no longer load?

I'm a bit annoyed that I can't even look at the builds people have made, and I was following a couple of them on my characters, and now when I load of the pages, nothing comes up. I was using them for a general idea, when I wouldn't otherwise have one.

Wouldn't it be a simple fix to just let us look at the builds from older trees?

They changed the way the characters and builds are stored, so that will no longer be possible. I'm sure if you ask nicely on the forums, the person will post an updated version of the build you are trying to follow.
