Unless have no MR, or you need the MR yourself, runaan's is better. 40 on-hit is ok - when you've already got the priority items that 30% crit should grant you the equivalent of 60 physical damage. and apply every other on-hit you have (ignoring aoe effects), meaning the E Nashors, if you have it, or wit's end too if that's somewhere in the build - and fervor for battle which doesn't benefit from the MR reduction.

Truth is, yes I'd rather go runaan's over wits end - but I'd rather go wit's end over nashor. CDR is easily runable, and I don't agree with the sentiment that her E needs 100% uptime, anyway - better that she's strongest while it actually is up, which means if she's able to take more hits while its up, she can play more aggressively and end up dealing more damage. Plus, the MR reduction is generally better than AP scaling on-hit, though she loses potential 80 AP from omitting nashor.
