I've seen this thread nuuuuuumuerous times, and I never thought I would make one myself, since making smartcast toggle on-off seemed like an actually good idea that was easy to implement and had virtually no downsides.

However patch after patch I've waited and for nothing.

I just want to know whether thats because Riot rejects this idea, or because they've been too busy to deal with a small problem like this, or whether they are already working on it.

Nope, it's a good idea that we just haven't had time to do yet. I personally think it would make smartcasting more flexible and accessible

For the most part I am use to it and dont need it but it makes spells like Victors E and Rumbles ult a little easier to use. Again I can still do it but, I occasionally screw them up.

Yay!! can't wait for it

LOL, sadly I don't get to decide what does and doesn't get done by myself, so no promises!

I think the biggest issue with this would be making it be extremely visible whether or not smart casting is toggled on currently. Requiring you to remember... not going to work.

This will add another item to the UI, and you have to decide whether that is adding more potential clutter.

I think I have a better solution.

So, you want to use smartcasting primarily and be able to view the range of spells when need be, right?
If so, why not place smartcast on QWER and regular cast on Shift+Q, Shift+W, Shift+E, Shift+R (ironically, the default smartcast keys)?
The Shift+key is a little bit harder to press and takes a little bit more time, sure. But you will only be using it in situations when you have time for it (if you don't, then you can't take your time to aim, then you're better off with simple smartcast).

The only problem I see with this approach is that you somehow cannot assign regular casting to Shift+key in-game - you need to change input.ini manually.

Doesn't it solve the problem?

P.s. I've been using this config for over half a year now, and haven't had any problems with it.

Okay, I get it now, thanks.
