I mean, take for example ADC item choice set: 
for example.
MAGES choice set:
as u can clearly see they provide perma MS buff.
while assassins :
get only out of combat MS when they should be the most mobile in the game.
is this fair?
IcyPepper3 votesYou might have a point, but I'm unsure.
Assassins rely on mobility, as in dashes and shit. They don't rely as much on positioning in a teamfight as much as ADC's and APC's do, who must position themselves properly in a team formation unless they want to be gangbanged by the frontline that will cc them for days.
Not saying that assassins don't need the movement speed, I see your point there, but the idea I thought was is that it was about positioning, rather than chasing and all that shit. If anything, there should be a river/bush movement speed item specifically for assassins only, allowing them to flank and roam easier than other roles.
