just got home and grabbed it off your repo, about to see how it does. Thanks man!
Edit: Just noticed, any reason why it spams unmend so much when I'm not the one to initiate the fight? I seem to be casting it 5-10 times before starting main combo. I can attach a log if requested, I'm not using any addons other than gourmetbuddy and default Fatebot
Edit2: Tried changing the 15f to 2.5f as mentioned earlier, checking if it solves, this is using the version I got of the repository meaning your repo isnt changed.
Try updating the folder, the zip is a lot older. It's definitely the right version on the repo, Revision 104. It should only throw an unmend once, and then periodically throughout the fight to try and proc unleash. What combat assist are you using. I only use the standard combat assist.
