When you say the lines are "not available to Halflings", do you mean halflings cannot take them?
A halfling fighter could use bluff, rather than intimidate to taunt. The entire two lines of the fighter and paladin tank enhancements are not available to halflings. I've tried a couple of times to make that build without any success.
Just to clarify, which group of elves are you talking about here?
Even the elf may taunt better than a halfling. Elves, IMO, are supposed to be the kindest creatures in D&D.
