User blog comment:StrategicMagic/Spirit Stone - Viable in Lane/@comment-7006769-20130426102252/@comment-5194571-20130426180302

I did say that the passive is not wasted, knowing it only works vs monsters. You may be laning, but if you play Cho like I do (max E, push with last hits, go farm jungle, rinse and repeat) then you are not wasting it.

Also, I didn't say I get it over philo. On Cho, I get both. I usually upgrade Philo into Shurelya's because it's just good overall, and a second burst of speed can't hurt. If I need damage, I can also upgrade into Ohmwrecker, also useful for seiging.
