There's really not alot of mechanics or even enmity problems in the lower levels, plus WAR gets defiance at 30. I would say he should be getting it by level 30.
Provoke pre-50 is entirely for re-gaining enmity (or pulling things from long distances), which most commonly happens by the tank dying and enmity being reset. It's recommended to get it >50 because of this reason - it's not fun dying to a boss, getting raised, and then not being able to get back hate.
