I have a little probem about how to build Yasuo. With my currently used item build i reach at the end ~90% crit chance. But of course it would obviously better to reach the 100% mark.

Current Runes are 5xCrit Marks, 4xAD Marks, 9xScaling Health Seals, 9xMR Glyphs, 3xAD Essences.

My currently used item build: Doran's Blade, Statikks, Berserker Greaves, IE, BT, LW and one defense item like Randuins, Banshee's or GA.

My problem is that Yasuo has just 80% critical strike with this build. With my 5% crit from runes I come up to 90%.

Is that already enough? Or shall i change LW for Trinity Force? Or better change Statikks for Phandom Dancer?
