As for tanking, it's easy.

War - Tomhawk, wait for it... OVERPOWER, maybe twice, then go through combos, then Overpower. Or if multiple mobs, Berserk/Internal Release/Bloodbath/Vengeance w/ Overpower SPAM till tp runs out.

Pld - Shield Lob, wait for it.... FLASH, maybe twice, Circle of Scorn, Go through combos, flash between combo sets.

One thing people oft times forget is you can switch targets to finish you combo. Particularly on Paladin (though patch may have made it less so) It was important for me to start a combo (Fast Blade/Savage Blade) one one target, then finish the combo (Rage of Halone) on a second target... and doing that switching targets and tossing flash out. To better spread hate. But kinda depends if your DPS is doing AOE or Single Target. Marking never goes out of style, except that you may get to a point that your generating enough hate to not need worry about it.
