Maybe a bit late now....
I have a lvl 7 Taliyah and these changes will probably make her gameplay less rewarding. Her e+w combo will be easier to land and it already does a lot of damage. The combo is part of the mechanical aspect of league. As for competitive game having the difference between players who can land and players who cant, will show the person's investment in a champion. The e+w combo is not easy to pull off with a tough opponent and landing it against these players just gives you, as a player, a compliment to how much you have practiced Taliyah. As for the possibility of option 2, it can be a nice tuning for Taliyah. I do remember messing up my combo because of the direction I launch my enemy to. Being punish for this is very reasonable and its part of the learning process.
As my stand point, Taliyah is currently in a balance position. A nice tune on her damage might be enough to give her opponents a room for counter play. But we also need to consider that when she is in her worked ground, her dps sinks drastically. It is her weakness and people should punish it, but it does not mean it needs a nerf. Having to think about the spacing and all is part of her kit. And this is probably the most difficult part learning Taliyah. A player cannot just use Taliyah's Q blindly. This applies throughout the whole game, laning, team fights, and so on. Her weakness is clear and also reveals the balance in her kit. Not to mention her Ult is a utility based, its a very situational Ult but it is in very rare occasion in use during 1v1 or team fights. Also another drawback. Though preferably a tuning on e, maybe her early damage or even mana can also be considered when she is in the spotlight for a change/nerf. There are a lot possibilities that Taliyah can be change to balance her overall. However, I do believe her mechanical aspect should not change. Theres a room for counter play and most of all its challenging, fun, and rewarding as the way it is. Welp..... it just my opinion though (o.o)ノシ
