The sword root needs to be fixed. However there are also a number of other skills that need to be fixed with the same issue. A lot of skills (actually, probably most from what I noticed) that you receive when transformed for things such as renown hearts and also the Norn elites will root you which makes them a huge pain to use.
I do agree that the sword issue is bigger since it is a profession’s auto attack and not a temporary skill set alteration, this is not an isolated issue.
