Allow it to be used in invisibility AND keeps you in invisibility. The only true time this perk becomes useful is when you are invisible and you need to take down a target with high priority. But really, they are usually either surrounded by lesser adds and their tracking ability makes it near impossible otherwise. It is not like it will be abused, since it only works when the charge is up. Also, it would finally allow us BD to actually feel powerful when holding our blade besides our Super. Thoughts?
