She fits practically anywhere, unless you're like those people who play Zarya and pop their ultimate with 0 energy charge. If you can't find a fit for someone with such a versatile tool kit as Ana then I have to call in skill level into question. Considering you will not provide any solid back up to your claim "pretty useless" except opinions of you and your friend, I'm left to my own assumptions. If you're not gonna provide a legit reason outside of she can't out snipe widow maker, then please move along and save providing poor information to anyone who hasn't tested her.
