WOW Gold: In raids, you can’t really go wrong picking a DA to tank for your group
Temple Knights: For raid bosses, an HP weapon is needed, but the TK can handle it in general with gusto. They don’t have as high con as the human tanks, but have Guard Stance and significantly more WOW Gold CON than the Dark Elf tanks. That combination makes them very useful under most situations.
Paladins: For undead raid bosses, there are none better: high HP and extra resistance to undead give the Paladin the decided advantage as the tank of choice. They have a 360 degree shield blocking toggle, which makes them very useful at fighting raid bosses with minions.
Wrap-Up: AoE parties are still a fast, fun, but risky way to gain experience. Even with the Chronicle 4 limitation of 20 mobs makes pulling limited, it's still quite rewarding. It allows tank to perform what they do best while giving healers and classes with AoE skills a chance to shine.
Dark Avengers: In raids, you can’t really go wrong picking a DA to tank for your group. They’re the only pure tank that doesn’t get 360 degree shield blocking of any kind, so the DA must either rely on his skill or luck to keep his shield between him and the gobs of mobs.
