User blog comment:Chase999/100% crit strike build./@comment-25055281-20150402125453

Ok, so an ecuation of the form A*B*C (bound by A+B+C) is maximiced when A=B=C.

This may lead to think that maximicing AS or Crit is the way to go, since those two are capped at 2,5 each (with 100% crit chance and IE).

The problem is how much AD you can get from slight reductions in either one...with some rough numbers and not taking into account champion steroids or Shen (but considering Youmuu's active allways on) I get about 1250 dps for your build, exchanging Trinity for BT my numbers are 1269. As I said, those are rough aproximations, but still lead me to think the real numbers wont be too diferent. Changing Shiv for BT yields similar results. In both cases damage is close and you lose something else to gain lifesteal and a shield.

Then you have to factor things such as the value of AS when you want to constantly move or cast abilities whit casting times, or the value of Crit when you want to siege turrets...and most important, the way Armor and Arpen affect your numbers. Also the importance of some stats depending on circumstances (wining or losing for example) and the point in the game (lifesteal while laning, midgame Trinity vs IE)

Personally, I feel your build does plenty of damage but lacks Arpen, laning without Lifesteal is not confortable and item order feels akward (I would buy Trinity and Shiv before IE and PD, and building Youmuu out of Avarice instead of Brutalicer is way weaker althought I understand it's about the gold)
