> **You do not need to install this yourself.** It comes with ArenaPlus, and it does nothing on its own.
This addon carries the data ArenaPlus reads: every rated ladder for US and EU, the live title cutoffs, the class and spec of everyone on them, and the gear, gems, enchants, talents and glyphs of the top five of each spec in each bracket.
## Why it is separate
It used to ship inside ArenaPlus, where it was half of every release — roughly 2.4 MB of tables next to 2.4 MB of unchanged code. Splitting it means the ladder can be refreshed as often as it is worth refreshing, without asking anybody to re-download the addon itself.
## Why it updates so often
Because it is only data. Every update is a fresh snapshot of the ladder — no code changes, nothing that can break. Take them whenever you like; ArenaPlus works with whatever snapshot you happen to have.
## A snapshot, not a live feed
An addon cannot reach the network, so every player reads a file that was shipped to them. The ladder here is only as current as the last time your addon manager updated it. Once it has, `/reload` in game picks it up without restarting.
Your own rating and rank are always live — those come from the game itself, not from here.
## Where the data comes from
Blizzard's own Game Data API: the leaderboards, the reward cutoffs, and the character profiles behind gear and specs. Nothing is scraped from a third-party site.
