This is essentially a split off of the arena features from SSPVP2 so if you're using that already then you won't see much changed besides that it now includes personal rating on the pvp frame.

Includes, modified player and inspect arena frames, highest personal rating on the same bar as arena points, general arena formulas (points -> rating, rating -> points, ect), and team summary when the match ends.

See the screenshot for an example of the first two features, slash command is /ssarena and configuration can be opened with /ssarena ui.
