Only...low level dueling is capped at level 29-30.
Nice counter attempt.
They have Stealth (Tal Eth) that increases cast speed and run/walk, but no armor runeword that increases all of the other speeds. Consider it a melee-esque version of Skin of the Vipermagi: trading off 1 skill, additional resistances, a bit of FCR, and magic damage reduction for other speeds and physical damage reduction.
Besides, is it really THAT much better than, say, Treachery? And do all runewords have to have a max of 7 properties? No.
to solve that heres is the layout of the runewords
