They don't like it when you double post...
Odds are they wont include an invinceability feature for transformations. It would be abused to no end, unless I suppose they put a lag on it. Again though, it seems like too much work for too little product. There should be something tactical about transforming. You should be able to do it in front of somebody who is about to fire a beam at you and just shrug it off. That's madness.
