Dragonflight Beta / 10.0 PTR support please!

[Voxxel]

ECB looks completely broken even the slash command doesn't work in the beta. I know this repo is for Classic but would you be kind enough to check this masterpiece if there's a way to fix it for Dragonflight Beta / 10.0 PTR please?

Some LUA bugs I caught so far:
