Oh Hell Yeah...
I have used most special attacks/maneuvers at one time or another and found, as others have, that it forces the PCs to think outside the box a bit and not just fall into the "You swing, I swing" pattern of boring-a$$ combat. Bullrush, aid other, disarm, trip, overrun, grappling and sunder are all valid maneuvers and can bring about a slightly more cinematic feel to combat.
One episode saw a an enemy fighter bullrush both frontline fighters into a pit trap. They both mangaged to grab the edge, but dangled precariously above the spiked pit. As the enemy fighter prepared to make shish-kabob out of them with his ranseur, the party sorcerer cast rope trick, swung across the pit, avoided the AoO and grappled the fighter. That is the stuff legends are made of
!
I think a great many DMs miss out on the opportunity to use tactics creatively with their critters (even catapult fodder like goblins, orcs and gnolls). Why on earth would a group of orcs pair off with PCs for 1-to-1 or even 2-to-1 combat? Aid other, bullrush, feigned retreat, charge with longspear and grappling make even individually weak opponents much more formidable.
