Smart cast or No

Smart-casting by default.

Think about it this way - You may miss judge how far a skillshot will go with smart cast on, but you might miss the same skillshot in another instance because it took you too long to activate it.

I started with the "hold key to see it's range", but that messed up Viktor's Laser too much (as in I could not use it at all with that option). That got me started doing full quick cast with Viktor's Laser, and many people will say that's the hardest skillshot to learn to quick cast. Well, then I was tired of toggling the quick cast every time I went to swap between Viktor and other champions, so I just turned it to full quick cast.

I have everything on smart cast... but i know some higher people take it off certain skills for better control.

I smartcast everything. Except for Sion's Q. That's the one exception
