when in the "stand alone" stance with the blue line "courageous conviction" trait active, words of courage no longer gets converted to "courageous heart" (which makes sense) however the heal cannot be used on self as the trait intends.
When using words of courage while in the stance, its cooldown is massively increased to match that of "courageous heart".
Just something to be aware of, at the moment the work around seems to be to exit stand alone, use words of courage, then reenter the stance, hope this helps!
