No to movement speed because 1% increase is worth a different amount for someone with Boots of Mobility, Alacrity and a base movement speed of 355. against 320 base and having Berserker's Greaves. The same goes for the flat amount with having % increase runes of a nunu buff etc. Also the soft caps make it even more unreliable to get a linear dependency.

Its like wanting to calculate the amount of damage done by AA's on damage alone if you do not know how much crit change you have and whether or not you have urgots/sona's damage debuff on you.
