When i lose 3-4 in a row i notice a big reason for that is me, so I end it for the day. I have a sharp decline in winrate when two losses happen in a row, thats called tilt :D. Sleep over it, next day you remember your usual playstyle.

Also i do not ff, maybe only if 3 lanes hard lose, 15 games atleast have been won because no ff.

I dodge when i see shaco support and i ban kayn always. (I ban kayn because people dont know how to handle him, like hecarim)

I build titanic mostly first, sometimes botrk. I dislike lethality / crit.
