The devs have done some "interesting" things in the past and are highly likely to do so even in the future, so until the future that is 4.1 have become the past I for one will not speculate or take anything as being assured.
Add to that this simple fact, they did not mention any potency changes so we have no idea how much jobs will be buffed or nerfed until the patch notes are here. Take the change to shake it off as an example, we know it will be some def buff for the party but how long the cd will be, how long duration it will have, or how much it will do I have not heard.
