I had this really random idea once while I was switching my build around for the millionth time, what if there were tabs you could enable to switch between your builds, kind of like the weapon set tabs we already have? It would change your skillset and your attribute points, and any builds that you can't access due to changing your secondary would be greyed out. You would still have to change any equipment yourself, but this would save people who use different builds to do different things a whole lot of time.
