PSA: it's the small things that make the difference on champions

some examples

using E then ult on anivia rather than vice versa makes your combo far less predictable and far more reliable

using Q + ult mid-dash on fizz makes your combo nearly unpredictable and ult the majority of the time guaranteed to land

using E + flash on ahri rather than vice versa makes your combo unpredictable almost every single time and guaranteed to land, assuming you aim right in the first place

just a PSA, these small changes make the difference on champions
