CoS nerf vs. prenerf

[Gustoo]

Doesn't matter.

Its a cool item to have. One less expendable item (invis rings) to consider. Takes 1 bag slot. If you play this class all the time and your buying upgrades for your character, at some point or another you will decide to get yourself a COS.

If you're more casual or want to twink other characters instead or whatever, ya, the COS won't make sense.
