Instead of giving this passive to 
, maybe a rune would be necessary? There are countless complaints of creep block and considering it's a legit mechanic, maybe we could just stop loading crit items with the mobility they don't really need :D and help everyone out.
um the ghost summoner spell?
Kassadin would need a buff since walking through minion is half of his passive.
It would be exceptionally abuseable. It would have to come with a movement speed decrease to make it fair.
Pretty sure phase rush and nimbus cloak do that
It should be added to inspiration, either under magic boots or the timewarp tonic thing.
Maybe unit collision hotfix and then implement passive as a rune if neessary.
