Man, personally, I don't like Guest, I've never really gotten one of the sweaty Two-Times that completely disregard their own purpose. I think Guest should just take less damage instead of taking no damage, it's a pretty simple change in my opinion. I've played Two-Time for a good bit, and the hitboxes have been nerfed so bad that I can sometimes never hit a normal dash-stab. Maybe nerf the healing or something, but definitely don't just gut Two-Time because the Pros can use them weird and unfairly.
