Shaco's Q Working With Warlord's Bloodlust

Hi! I had a question about when Shaco uses his Q to go invis and get the guaranteed crit. It seemed before that when you used this to crit it would work with warlord's bloodlust and give you the heal and attack speed, but I just finished a Shaco match and it wasn't working like that anymore. I don't know if it's a bug or if it was patched or what so I decided to take to the forums and ask for help! Any insight would be great! (Also, sorry if I'm in the wrong thread it's my first discussion so I wasn't positive where to post it)
