Even after 6.11 Taliyah needs some love and buff

I really like Taliyah's mechanism but she is a little bit too weak even after 6.11's buff. She's laning phase is not bad now, and she still have strong mobility and CC to gank other lanes. But she's weak in fighting against assassins and playing team fight.

1. For assassins, I know mages are all afraid of assassins, but Taliyah plays worse than other champ. Indeed she has W to knock others away, but it's too unpredictable and delay too long, which makes her usually dies already before w comes out, also her E has no damage at all when they jump in. So here I suggest to buff Taliyah's E to start from her back a little, like Azir's R, to effect chamions on her back. (Shurima's abilities are good to have some connections, right?) Also lower W's delay by level is a good way.
2. For team fight, she has so many CC, mobility to change the game, but not very good for 5 vs 5. One is that she's Q has punishment on worked grounds make her so bad on poking, especially before turrets or drag/baron fight; the other is her w and e are too short, make her positions in team to close to the frontline, ironically she is so squishy even with ROD, relai and zhonya. Her R are basically useless in teamfight unless enemies stand too far away from others. So here I suggest to make her Q's punishment weaker, Taliyah can throw more rocks on work grounds by level (1/1/2/2/3 may be?) to buff her poke ability. This makes sense because she keeps learning to control her ability and she can control it better by leveling.
