What if we had a champion with an actual combo system in their spells?

For example, you use Q, then you have the choice of using Q2, or W2, or E2, or using R2 to end the combo early for a specific effect depending on which combo number you left off on (1, 2, or 3)

You use E twice, then you can use E3, Q3, W3, or R3. And so on and so forth.

How cool would this be?

Imagine the champion's weapon could transform too. Like imagine Q would be sword attacks. W would be Scythe attacks. E would be gun attacks.
