I get this message every time I go in game. Brewmaster tools is on curseforge but file has been removed. Do I need this and if so where can I find it?

This has been updated in the latest profile. You can download it from here on github or, if you use the Twitch client, set the addon type to Alpha for Hero Rotation. You can do this by right clicking Hero Rotation, going to Release Type, and selecting Alpha.
