Actually, it's worse than you make it sound. According to Xypherous, Eve will get revealed by a tower if her champion detectable range overlaps the tower's reveal range. Which I think is fundamentally wrong.
I'm not sure what I said to give you this impression - this is flatly false.
The tower simply has more vision radius than before - There's nothing in her stealth system about overlapping circles.
EDIT: Oh. I see, the OP in that thread was making that conjecture. My apologies for being unclear then. Let me post a followup update to that thread. Thanks.
