These two items have the exact same stats. I understand that the Allagan boots were changed recently and then changed back due to Summoners. Wouldn't it make sense then to change the Sorcerer's Crakows to have the new stats that the Allagan Boots of Casting had?

It's boring that I only have one level 90 foot slot to choose from and it doesn't make sense that the rest of the Sorcerer's set gives spell speed and the boots do not.
