3 suggestions about Normal Cast and Quick Cast

I would be happy if you make some additional options about casting abilities and inputting combos. ​ ​

1. Cast on click press, for Normal Cast. ​ The current mechanism of Normal Cast is cast on click 'release'. Let me take an example of me playing Lee Sin and trying to use the 'ward - safeguard' combo. First I input the warding totem (normal cast) hotkey, and the range indicator is shown. Here I have to 'press left click - release left click - press W...' to complete the combo. The problem here is that, if I press W key before releasing left click, the casting of the ward is cancelled. Creating a 'cast on click press for Normal Cast' option will help people suffering from this problem. ​ ​
2. 'Cast the pressed spell upon pressing another spell', for Normal Cast as well. ​ This is another solution of the 'ward - safeguard' example above. Pressing W with left click pressed makes the system recognize the inputs as a combo and finish the casting of the ward. This feature already exists for Quick Cast, and I believe this is too good a feature to be only applied for Quick Cast. ​ ​
3. Add a 'Quick Cast with Indicator' option in the quickbind UI - which leaves 3 customization options (Normal Cast, Quick Cast, Quick Cast with Indicator') for each ability. ​ For example, I want to use Normal Cast for Ability 1, Quick Cast for Ability 2, and Quick Cast with Indicator for Ability 3. Adding a 'Quick Cast with Indicator' option enables me to do this and can broaden players' possible choices. ​ ​ If you add all 3 options above, or at least 1 or 2 of them, I would be very happy and I believe it will help a lot of other players' improved gamplay experiences :)​
