Make Doppleganger worth something

[dragonsbane24]

<p>I hope that a Dev reads this and would look at making Doppleganger useful as IMO at this state it is of no major use in gameplay.  What i would like to see is have the ability to dopplegang another character for a limited time and gain that persons or classes abilities for say 45sec or something and make it a aoe immune pet for that time frame.</p>

I would almost settle for knowing how much it actually wards or how much damage it soaks up. As it stands you go...uh...oh...tank is about to die...start casting...five minutes later its up....to die .5 seconds later. Awesome!

Srsly though devs...would at least instacast on this spell be asking too much?
