Why are so many champs that built PD in s2 switching to Shiv for s3?
The cost difference is only 300 gold, and PD provides significantly higher AS and Crit chance at the expense of a single percent of MS.
That's clearly in favor of PD, so the answer has to be the passive - except champions building these items are almost always ranged AD carries. As such, positioning is critical and wave clearing is already very powerful, so doesn't the PD's unit collision passive make more sense then the Shiv's multitarget passive?
Is it because the damage is magic, which makes the carry less susceptible to armor nullifying their damage? Carries building these items should almost always be building ArPen, but never MPen, so this seems counterproductive unless in a heavy AD teamcomp where the opposing team isn't building MR at all.
Is it because the damage can crit? Even with an Infinity Edge, this only goes up to 250, and, as before, can be mitigated my MR.
Is it because, with high AS, it procs often enough to significantly increase the champion's damage output? Even so, isn't it unusual for most champions to take more then one AS item? The usual ADC setup I'm familiar with is one item for mobility, one for crit, one for AS, one for LS, one for ArPen, and one for defence. Now, obviously, these can be adjusted as needed, but wouldn't the loss of one of these other items offset any potential gain from the Shiv passive?
Shiv builders, what are your thoughts on this? What advantages do you see in this item over the PD? What situations do you use it for?
