User blog comment:The5lacker/The crit stacking meta: Why this needs to stop/@comment-9713132-20130408134126

I understand what you mean - I've seen Stattik Shiv come up as a rushed item, and it's actually quite effective if you understand how to constantly charge the item up.

I don't think it's the idea of rushing Crit Chance, but the fact that Advanced / Legendary items (aka. your build path) that have Crit Chance, also have attack speed. It's not the idea of stacking Crit Chance, it's the meta of stacking Phantom Dancers, with Stattik Shiv alongside as well. This is Attack Speed + Critical Chance, not purely Critical Chance.

At 80% Crit Chance (I will assume that you've taken two Phantom Dancers, Stattik Shiv), that is technically a 180% increase in overall damage, technically. You could have bad luck and not get a singe crit-strike at all, or the complete opposite.

However, the increase in damage also rises with Attack Speed - the three items together give a 140% attack speed bonus. That means you deal 240% the amount of damage with Attack Speed alone.

I uh, don't know the final calculations (I'm not sure if it works additively or not), but basically, it's a massive increase in damage. Supposedly, it'd be 240*1.8, which would then be 432. 432% increase in damage, if I stand correct.

So yea, I just want to quickly say that crit-stacking is theoretically wrong, but it doesn't exist in LoL (unless you stack Cloak of Agility, then yes, please don't do that) - it's actually quite effective. I've did one normal game once with just PDs, Stattik Shiv and one Zephyr (alongside Berserker's Graves) + a Guardian Angel. Worked reasonably well enough to make me say I'm happy with this style of gameplay.
