I wouldn't say irrelevant from a PVP stand point, (for PVM, maybe), as of today, in most pre-renewal servers, not having outrageously high base and job levels, WS still hit hard as CT still does a lot of damage, if the right/good equipment permit, the only draw back of the skill for me is the one cell range it has since WS are whole lot softer than any other tanks out there, heck Stalkers tank better than them in my perspective.
Nothing to say about AD Creators only that it hurts whatever class/monster you are.
