Actually, weaving solutions would make a difference for White Mage. I mained AST a bit, and I was so happy to move at the end of my Malefic cast, and still be able to Draw, or any oGCD.
When I do some roulettes or normal raids in WHM, I feel so SSSSSLLLLOOOOOOWWWW.
A slight pDPS buff and a 1.5sec cast time on stone could have fixed it in 4.4 - I don't see them doing too much for 4.5.
