CoS nerf vs. prenerf

[Vaarsuvius]

Being able to invis at will while running through a zone (wiz landing spot in Skyfire comes to mind) is invaluable,
In zones packed with mobs & roamers like Chardok or HS, invis without having to stop, cast and draw even more aggro
Flop, stand & invis at once to lose aggro. Too bad there's not IVU insta clickie (to my knowing)
can even be used to reset GCD (yeah there are far cjheaper options for that [You must be logged in to view images. Log in or Register.] ),
charm break,
trash buff,

I would not sell mine either whatever people offer
