As a basis from an EQ player, in comparison to FFXI. Pally/war in FFXI is the ultimate meat shield. In EQ, it the Warrior. In the high end EQ game (65 +) most groups try as hard as they can to find a warrior as tank because first, they have the most hit points than any other class, and second, the highest AC (armor class). Secondary tanks would be a Pally, or a SK. There are no other medians, there, berserks can't take for anything, much less hold aggro. Pally's and SK don't have much trouble holding aggro, but still can't tank nearly as good as warrior of the same calibre. No other class though would attempt to tank unless it was a lower lvl 65 zone like Bastion of Thunder, or something where a Beastlord or Monk with the right defensive Alternate Ability points could get away with tanking. In places like the Elemental Planes or Omens of War zones or Gates of Discord zones the only people that will tank period are Warriors/Pallys/or SK's...and really only Warriors 70% of the time unless the group cannot find one LFG. This might be completly irrelevant to EQ2, but I think some of it might slightly bleed over into EQ2 in some manner.
