Taliyah - Vector Casting, W/E combo, the second cast on W is gone? Help.

I not gonna say I was a Taliyah "main," I mean, shes not been out long enough for anyone to main her. But I'm also not gonna pretend like I haven't had 14/1 or 7/0 on some games with her either or taken her both supp and mid. In fact for my last 19 games with her I have a 57% win rate so I feel like I'm pretty on par with her current win rates in general. I think.

BUT, is it just me....or is something wrong with her W? or maybe I don't understand what vector casting is since I've never played a character like Rumble. I was under the impression that casting her W wouldn't lock you out of her other spells now, so that you could say: click cast/click choose a direction W ("okay I'm gonna shove them towards me and because of vector casting I can cast Q or E at the same time") click E and get them to explode on the mine field WHILE the W is activating. Excellent! Takes the whole E "set up" out of the picture!

But now its like Click/Drag? and the W doesn't telegraph to the player as well? where exactly did I place the seismic shove and should I commit with the follow up Q or E not sure wither or not I'm actually gonna push the enemy champion into my combo.

Is there a "new" way I should be setting up the combo? Is there a way to get the click/click back oppose to the click/drag?
