This list exaggerates her qualities. She does not have this many strengths.
One of the best roaming capabilities (if not the best)
Eh. Gotta dispute that. She has speed, but she doesn't actually bring anything to a roam besides damage and very weak CC. I'd rather have an ADC roaming with either longer range burst or some CC to gank. She can farm side waves effectively, but there is a lot more to roaming than that. She's decent at it, but it's not a great strength.
Can deal with tanks without Bork.
Not so sure about that. Tanks generally do fine against her because she's very easy to get on and just open her up to punishment from their teammates. She also doesn't have steroids that synergize with other ADC stats, which hurts her DPS.
Can be very slippery in a fight.
No she can't. She's one of the least slippery ADCs in the game. The strut on the W active isn't enough to make her slippery because of how quickly it gets popped in any fight. Any ADC that has any other form of mobility is more slippery than MF. Hell, a lot of the immobile ADCs that actually have good CC are more slippery than her. She's maybe above Varus or Ashe, and even that is disputable.
Never falls off at any point of the game. (she may not be a hyper carry, but she should not be ignored either.)
Yes she does. She's one of the weaker late game carries. It's not quite as bad as Corki's or Kalista's, but she's close behind them.
The AoE ult and the lane bullying are really the only things from that list I'd put as strong unique qualities. They're good, and the ult is kind of hard to replace (although some like Graves can take over her role very well in an AoE comp), but they are really the only unique things she has.
