It depends on the server. There are some servers where being "famous" will draw large groups out to cause as much grief as they can. However, there's a difference between wanting to grief the local 3-boxer and wanting to grief the local 25-boxer. A lot of players who would otherwise join in may decide not to bother because they're not interested in being repeatedly flattened while they wait for enough reinforcements to arrive.
Just gotta try it and see.
And I agree that a paladin may prove to be the better tank, they seem to be able to keep aggro on multiple mobs with less effort. Warriors have a number of abilities that they need to use repeatedly in order to keep a mob on them. For a paladin you just cycle through one or two and you should be okay. Plus you can bubble the character that takes aggro from you and you have another one-button-taunt ability as well.
