I've not noticed much of a difference in CC personally except that I tend to survive against SAM and DRG more, but I chalked it up to me finally learning to avoid them when they're obviously LBing. Monk got buffed though, and NIN had their speed nerfed a bit, other than that I dunno if there's been noticeable change in things. BLM got squishier, RDM got a slight nerf, and BRD can jog slightly faster while casting powerful shot.
I guess the line of sight changes have made it harder to run for cover and recover, which is probably a bigger struggle for melee since they must run further?
