New champion close to useless

The new champion Taliyah is close to useless. Lets list the pros and cons about her. Pro's

1. Q is a good kiting mechanic and really fits into the game
2. E is a good zoning tool and works really well when used to its potential

Con's

1. Her passive is basically useless giving little percent movement speed and you are basically in combat the entire game
2. Her W is really derpy and the mechanics of it is really difficult. The delay shouldn't be there. It should work like a flick like mechanic that goes off immediately.
3. Her ulti seems basically useless. When will you actually use it other than to zone an enemy? Also theres a lot of champions that can simply jump over that wall as most champions have some sort of mobility to do so.

Thanks and let me know what you think
