Warlords Bloodlust not work on Teemo

I see that there are already a few posts about this so apparently it's not just Teemo. Nevertheless, I decided to add this just so Riot becomes aware of this issue by giving my experience. So I was playing Teemo and I noticed after a while that Warlord's Bloodlust wasn't working all the time. I thought it just wasn't working in general, but I recall seeing the buff pop up one time in the match. This makes me think that it is working and there's merely a single caveat that it inhibiting it's activation. No need to respond to this as it's just meant for Riot to see how this problem isn't an isolated one.
