Welcome!
I'm not an admin, they might be able to tell you more, but I've never been able to navigate the mobile version well. What I do is request the desktop site and use that from my phone. It doesn't show everything, but it's easier to see things than in the mobile format, for me at least.
Welcome to the community, Angron! Glad to have you with us! :D The roleplay build tag is a relatively new one in our site's history. We only started recently using that as a separate tag so we could identify RP-heavy builds. This link will show you all the builds that have that tag: https://tamrielvault.com/group/topic/list/tag/304/group/3
However, if you want the entire archive of all builds use this discussion:
