If Teemo's fantasy is his shrooms, isn't that a failure of fantasy if anything?

I'm writing this to address what I think is faulty reasoning with the people who disagree with the Teemo changes that have just hit PBE. Primarily, those who say that Teemo's fantasy are his shrooms.

If Teemo's fantasy is literally his shrooms, isn't that a failure of his character? Yes, the shrooms are a big part of his kit, but Teemo is not a mushroom. He's a yordle, a rather dangerous on while at it. Teemo is the rabbit in the cave that you need to use a holy hand grenade on. He's unassuming, but he'll poison and kill you before you have a moment to assume anything's wrong. As a character, he's not "Master trap maker". He's a soldier, funny as it is to say. He Should be more than his shrooms, because those are one of his tools, not his only tool.

I understand the satisfaction of the shrooms, even if I disagree with how much fun I'm having from losing half my HP cause of daring to walk around the map, but Teemo's fantasy shouldn't be his shrooms. He's a soldier, he himself should be taking names. If Teemo's entire fantasy is based around his mushrooms, than why is it only one of his abilities? Teemo's fantasy is not mushrooms, it's about poisons and being a sneaky motherfucker. Mushrooms fit within that fantasy, they do not consume it.

I know folk will disagree, and that's fine. It's completely up to you to play a character for whatever aspect you like. I play Kayn because I enjoy the humor that exists between the pair, similar to how I enjoy songs with humor in them. But understand, while Teemo's shrooms are a large part of him, they are not Him. The rework definitely needs some changes, especially the oxymoron nature of Move Quick and his new Camo, but if there's any part they should suction power out of, it should be his shrooms.

For both Teemo's sake, and for those who have to play against him. If you think I'm wrong, Fight me, feel free to say why.
