I try to think of all scenarios when judging balance,
i think Ghost is going to be extremely helpful against archers, they do now have trap and turret to combat it how these things play out we will just have to wait and see.
I think ghost offers a nice chance against wizzies. Allowing the sin to stay within close Ss range waiting for shield to drop, its about time a sin could do something vs a well kitted wiz.
Tao im not sure about, will ghost hide from pets? If they already have master target..
What benefit will it have against warriors? Im not sure, sins usually get the first hit anyway but get flopped in 2 strikes if the war is sensible enough to stack +4/5 ACC. If anything it will be used to run away and hide....
Have i missed a use for it?
