"Pallies [sic]: are the only tank class that can split camps without help"
Don't forget that Shadow Knights can split by using feign death. Granted, that takes a little longer but it may be safer in the long run. A general rule with the Lull line is you shouldn't use it if you couldn't survive pulling the entire room, because sooner or later Lull WILL resist and bring the whole room down on top of you.
Shadow Knights also have the best ability to tank multiple monsters at a time. Paladins tank multiples only with difficulty, and Warriors only with difficulty *and* some luck.
Lay Hands is the only instant-cast heal currently available. Paladins could be considered 'unique' by virtue of being the most defense-oriented of the tanks. Consequently Paladins bring the most options to keep their group members alive when things go bad--be it root, stuns, heals, or the group member just having more HP due to the Paladin's buffs. Warriors can....sit there and watch their groups die, and SK's can feign and laugh to themselves as their groups die

Due having an arsenal of zero-damage aggro-generating spells, Paladins also have great ability to generate hate on mezzed targets from across the room, much to the CC'ers relief.
When I think of SK tanking, I think of sheer colossal hate generation on single or multiple targets; when I think of Paladin tanking, I think of *control*. Disease Cloud, superlative aggro as it is, by nature prohibits mezzing of mobs once the SK dots the target. Paladin threat generation doesn't come with that drawback.
Warriors are of course the meatshield par excellence--if you need a big fat target and don't need it to do much of anything except stand there and get hit on the head by some big greasy monster, the Warrior's your go-to man.
