Nurse does not belong in dbd.
First of all! Im ok with any other killer, but nurse is just a character that doesnt belong in dbd. She completely ignores main game mechanics, such as chasing, pallets, windows, WALLS. She can be hard to learn at first, but when you practice a bit, then it will be easy mode for you.
High mmr on pc is like 60% nurse, 20% spirit 20% blight. That should tell something i guess.
How can we even have Clown (for example) and Nurse in one game? They are such different strenghtwise, which is without a doubt very noticeable.
