Can I just say that Taliyah is a FUN champ?
I mostly play as a support in ranked games with my friends, but when I take a break I go to norms and I play Taliyah because I find her gameplay fun.
I've only played her three times, so I'm not good by any means, but I think it's fun trying to land your combo or make good plays by roaming.
I think her combo is more satisfying to me because you can see it all, unlike an assassin who make people disappear and you don't really know what killed you. With Taliyah you can see all the rocks destroying you piece by piece.
I think Riot did a great job on her!
