Shadow reflection takes 8secs to do anything, it doesn't auto attack or any poison dmg its cc will dr honestly I think it will get changed simply because it sounds terrible for assassin/combat unless they work massively different. That crap aoe finisher sounds like it could be good for pvp. First for it to be a option over the other 2 talents its going to need to do some big dmg for its cd and energy cost and it does shadow dmg so it will do the same dmg across classes. To me it sounds like a 100% fw evis for pvp or maybe a even stronger than a 100% fw evis. CT is just a aoe dot finisher death from above from what was previewed looks like a single target move with some cleave with all the dmg upfront.
But with it all we'll have to wait for beta and see with the health and healing and dmg changes its really to hard to tell what will be op or trash with this on top of if talents even make it to beta.
