Hi!
I find that I haven't used my Black Spirit One-Two-Three in what feels like ages and that's usually due to it being cumbersome to control when to use it. Earlier I found that my bar often tended to be full just as there was only one or two mobs left, making it a massive overkill (well, massive as far as Shai goes anyway). Granted, we can control this by toggling the Black Spirit skills by pressing ALT+B. For me, this is impractical to say the least, especially during combat and as such my Black Spirit skills are always locked to prevent accidental activation resulting in them instead never being used -.-
Suggestion: Allow the Shai to quick-slot the Black Spirit version of One-Two-Three while allowing us to lock the RMB-trigger part of it.
