If you think that, then you're very silly.

To theorycraft is to build a hypothosis or idea based on what you see, hear, experience, and relate with others.

Example? Take the following: [Vayne is OP, needs nerf especially to silver bolts].

"Vayne is OP, needs nerf"-- this is the observation, so the theorycraft is "to silver bolts". There are no numerals truly being assigned here, just that the current ability itself is too good conceptually or numerically to the person writing the statement.

Another example would be [Draven is the best ADC because he's fun].

"Draven is the best ADC" is the THEORY, and the observation is "because he's fun". What makes Draven fun? Spinning Axes. What makes him a potent ADC? I'm not sure, but it's probably his Spinning Axes or his ability to farm insanely well-- which also comes from Spinning Axes.
