Putting it into an active ability gives warriors ANOTHER damage reduction cooldown, when we're already replete with them. On my warrior, I have:

Chain those together and you have huge stretches of time where you're really hard to kill. If we give warriors yet another cooldown, or worse yet, a whole lot more passive damage reduction, Blizzard will have to design bosses under the assumption that you ALWAYS have some sort of damage reduction cooldown on you. That kinda sucks.
The 6% more parry during shield block adds something to the ability which already has block chance, crit block chance, and magic reduction on it, but the ability still only does 2 things: mitigate melee swings, and mitigate magic damage. Adding parry just makes a fairly strong cooldown that much stronger.
It's like buying a car that gets 30 miles per gallon, and being told that they'll upgrade it to make 38 miles to a gallon at no extra cost. It's a win.
