Since Celerity (rune) is being opened to more champions,

Tooltip is bugged. The bonus MS effectiveness is 70% -> 7%.
Why not partially revert it to its previous state and remove the AD/AP, letting stay only the bonus MS? There are a lot of champions who don't have MS bonuses but could use a MS rune (some supports, juggernauts, immobile mages, etc), without needing to rely on Magical Footwear.
If there's a problem with making Celerity give a free stat (like causing it to become a boring and uninspired choice), then just put some mechanic like the Energized effects or some other conditional stuffs; but regardless of that, make it give bonus MS, not increase the effectiveness of MS boosts, since by giving bonus MS it would automatically synergize with speedy champions (
) AND be useful for people who don't have MS boosts, increasing it's usability.
