Here Riot, I fixed Eve for you

Passive: Added - can now be spotted by wards while invisible. This does not cancel stealth (meaning she will remain stealthed the second she gets outside of ward range unless a champion gets near enough). Ultimate: Added new passive effect - reduces the area wards can detect her while stealthed by 40%/70%/100%.

There. She can no longer ignore wards early game, wouldn't be completely fucked over in team fights by someone just dropping a trinket ward, and can be buffed in other areas.
