Taliyah feels very underwhelming
That's a whole lot of skillshots for not a whole lot of damage. Utility mages are supposed to provide utility for the team, but she only hosts a small knockup and a moderate slow field? She has the wall but it's a pretty situational fighting tool at best.
A lot of utility mages seem to offer more than her, and are easier to use. Karma's a perfect example. Everything Taliyah does, Karma can do better. Sure there are some situational nitpicks but overall, Taliyah is just so underwhelming right now.
