Johns for Green Lantern, Aquaman and to a lesser extent Shazam/Captain Marvel
Rucka for Wonder Woman and Cheetah
Morrison whenever he gets ahold of Superman. Also his run on Batman was a breath of fresh air with Crazy Awesome but likeable BatGod after years of insufferable Bat Jerk.
Tim Seeley and Tom King for Dick Grayson
Seems to be inevitable, sadly. For my list, Dick's back in a serious rut. Hal has fallen into one somewhat as well, though to much less severe degree and he has Morrison coming up at least.
