The tear is my favorite item <3.
Also, I seem to not understand why people like the Ninja Tabi so much. Unless the champion already has high dodge stats, its kinda worthless, right? The +armor is nothing in comparison to other +armor items, and +dodging in general is only good when stacked with other +dodging things... at least in my own experience.
And I stopped getting 5g/10s items recently, unless I'm not building anything off of my starting items. Although, I'd much rather get a philosopher's stone over anything with "Doran" in the name.
Nimbleness. Without any other dodge stats its around 12-13% base dodge, which in turn means that much for a 10% boost in speed. Now factor in how many times you are fighting with some creeps hitting you, and you can almost count on that speed boost to be up most of the time. And dodge = 0 damage. Quite nice when instead of taking that 600 damage crit, you take 0.
