The famous (and imo, far superior) arena frame AddOn GladiusEx - now for WotLK 3.3.5!
The AddOn will not work on Classic WotLK, it will only work on the original WotLK client.
To download the addon, go to the release page and download the latest version as a zip file. Unzip it.
Note: If you're daring, download the pre-relase version and provide feedback.
The Addon is to be placed in /Interface/AddOns (relative the WoW root folder).
Do not use the Code -> Download ZIP - it will not work. It's only for developers who know how to use git submodules.
If you find a bug, feel free to report it as an issue. Don't expect immediate fixes, and some proposals will be rejected (GladiusEx is an arena AddOn, not a complete unitframe replacement AddOn).
Supports spectating based on ArenaSpectator (or variants thereof) which is available on some servers. Don't expect it to be perfect.
The "Incoming" Absorb/Heal portion of the healthbar module has been removed as the underlying API is non-existent in WotLK.
The "Cooldowns" module is only in beta mode. It works, but some abilities might be missing / having an incorrect spell ID (thus not working) / have an incorrect CD / be missing some conditional. Feel free to report specific improvements that can be done, or create a pull request in LibCooldownTracker-1.0 (3.3.5).
