The title 
says everything 
.
I know other skills are quite buggy too but oh well.
Also I can use thrust/bash (if I learnt thrust) with 2H sword and clones do use the skills while 2H sword is equipped.
Must be because of their current unique property of not being able to copy your moves if you’re using the off-hand weapon
In this case, the 2H counts as both the main-hand and off-hand which may be the reason why this is happening
But is this intended or considered a bug? Seems weird that they would want to disallow clones to copy 2H AA
