[Gameplay] Few Tahm Kench bugs.

Hey Riot, Im a main support in EUNE, but that doesn't matter, the thing is, Since Tahm Kench got out, I figured few bugs on him, since I play ONLY HIM since he's released Bug Number 1 (Easily Abused, Fix it fast please) : There's the combo of Tahm when you Press Q and then Immediately W to Devour an enemy minion or jungle creep from far away, when you calculate mana costs (Q = 50, W = 90 therefore the combo costs 140), when you use this combo you only use 50 Mana, just the Q mana. Bug Number 2 (Again, Easily Abused) : W (Devour) states that when you devour an ally, when you run towards enemies, you gain 40% move speed, but I figured that no matter where you run, you gain this move speed, Giving Tahm an un-needed buff. Bug Number 3 (Just annoying bug) : Again, With Devour, when you Devour a friendly unit, Like the Champ spotlight, they should control where theyre going, but they actually cant, making me work a bit harder in our ranked 5 games :( Bug Number 4 (REALLY ANNOYING BUG) : When you Devour a minion, you are able to spit him on the enemies, but when you do it too fast, the minion stays where you are and not going out forward, that reduces the poke production in lane. Bug Number 5 (Again, Annoying bug but I didn't manage to make it a lot) : When you devour a minion and spit him out, there's a slight chance he becomes invincible, you can't kill him for a few seconds and that is very. very annoying because in a game I had, we were losing and I wanted to wave clear, but I make a minion invincible near our nexus towers, and he tanked one of them and let it get hit some more, that shouldn't happen. Please fix Tahm, my only love.
