Tahm Kench Bugs

I'm having some bugs with Tahm Kench mostly similar to what others have posted.

Q - Tongue Lash: Supposedly you can press W to devour minions and small monsters "While your tongue is in mid-air" , however I have been unable to make this feature work despite going to great lengths to time my button press to individual frames of animation. This may correspond with issues to Devour.

W - Devour: Not sure where to begin with this one really. The skill seems rather unresponsive at times, requiring me to click 3-4 times on what I want to use it on every now and then. When i have a minion or an ally devoured I still get an AoE display as if I was trying to eat something (if this is intentional I don't care, it needs to reflect the real range they can be spit.) I've also noticed if I have an Ally devoured it doesn't mater if i run away from the enemy or not, I still get a speed boost. Not that I'm complaining, since that's way better for me as a support but it's still a bug if that's not supposed to happen. I also believe that this skill may be the reason behind my issue with Tongue Lash.

Another bug that I found out was this.(In the pic)
