Yeah tried to search fast without any relevant results so decided to make own whine thread just for this one nano, if its already covered well somewhere then feel free to ignore/delete this one.
As it is now, about half the time i use it, i dont get any crits, just get the 7 minute recharge. Its highly annoying if for example the doc you tried to alpha barely survives with tiny amount of HP while you notice your crit buff didnt work and just one crit would have done it. And yes, i did hit the docs during the 6 seconds of the supposed crit time of the nano, with regular hits.
Seems the more busy and fast the situation is, more likely that nano fails to execute, so maybe you have to be totally still not doing anything for a second or two to get the desired effect, but when ganking someone in middle of hostile crowd, you dont have time to just stand there doing nothing to make sure your toolset works properly.
