Most champions that have a line-attack spell like that (short-range, long-range, whatever)...
If you (a) put it on smartcast, and then (b) HOLD DOWN the q button, it will show you the cast range indicator
For example, put Zyra's e on smarcast and then HOLD DOWN the e button
-> You can now see the cast-range before actually casting it
--> You can even move-click to cancel; if you didn't want to cast afterall
Yasu, right now, always casts the q, whether you tap it OR hold it down. It makes aiming the tornado (or the short-range version of the #1 and #2 q's) a pain in the ass, since you can't tell what the max range is
-> Unlike every other smartcast spell in the game
Please fix, thanks!
(btw, this champion design is incredible. Let me come to HQ, I buy you guys a beer! Yasu2g!)
This has been fixed on most current version of PBE
The 3rd q (the hurricane), is an aimable smartcast, just like the "hold-down-able" Zyra smartcast E I mentioned
