That doesn't answer the question though. Why when you turn on extended tooltip do you lose information? You can see damage with it off but not with it on. It makes playing with it always on (like I and many others do) very difficult to quickly determine things like Karthus R damage for example, instead you have to do the math yourself. Why does every employee outside of Reinboom that's replying here and on twitter completely ignore the question and answer something else instead?
Sorry I didn't get the answer in the first one. Its a matter, like you said, of being able to find that information quickly. The formula we have to write to include the total and the ratios and the amount from each stat becomes very cumbersome in many spells with multiple scalars. It becomes very hard to scan for the information you actually want when some of these formulas can take a whole line. Advanced only tooltip users will have the option of quickly finding that damage by using shift to swap their tooltip back to the simple one temporarily given that they know the information they're looking for. I agree in this case it isn't the ideal way to get that particular information, but it is fast and it helps us show more information.
