Fountain Killing Issue (Issue with current mechanics rather than bug?) [GAMEPLAY]

This is less of a bug, more of a problem with the turret mechanics in the fountain.

In the video, Ryze teleport minions into the fountain, no big deal, that's a creative thing to do to at least stall the turret. However, Jax was teleported in WITH him, and the turret doesn't attack him. That's fine, it shouldn't immediately kill him as he was in the minion wave, although it should prioritize champions as first target in a chain rather than minions if one wanted to keep enemy champions out of the fountain, but that's more of an opinion.

But then Yasuo jumps in and kills Xerath without getting turret agro at all, not even when walking out. That honestly feels like a punch to the face that it doesn't have normal turret reactions, nor does it clear minions fast enough to deal with that situation realistically.

For step by step, simply have a Ryze ult minions into a fountain and attack a champion within the fountain while the minions are under fire, optional teleport the champion themselves into the fountain with that same champion attacking the one in the fountain
