I have been getting by without blade dance (or furious chase) in my ring menu combat hotkeys because my understanding is it is not available , you don't see it as an available skill selection like Blade of Blood, Wind Orchard, NEther Bloom, or S. Purge, or even Sacred Dance, for example.  Instead I use Blade of Blood, but it is longer and slower, and really purposed differently, not so much for a quick start but for the lingering SA effect. 

Considering many of the succession combos for PC use part of blade dance, sometimes even twice, for a stiffen, will we get additional ring menu selections? Or, is there a way to change the skills available for menu and I am just misssing something altogether.  If not it seems Lahn Succession will be lacking when it comes to extended combos.

There was another player having this issue as well, and its because the skills they were trying to hotkey were locked. Check that, and if you are still having the issue after you look into that comment back below, and I will get it added to my bug report! :)
