To continue, did we not learn that gap closers and jump backs with potency are just in general not a good idea? They have long caused many other classes problems but this time Ninja is the first class to get them as GCDs instead of OGCDs. On top of that, they're a combo skill that is breakable by using literally any other weaponskill so we cannot hold them when it is dangerous to use them or we will lose them completely.
