When it comes to the warlord, a good defense is the best offense. His shield and blocking abilities make him hard to hit, but it's his counter attacks that make him so deadly. His Full Block stance gives him survivability against multiple opponents, and once he enters revenge mode, his low stamina ceasse to be an issue, as his rage allows an endless number of nigh unblockable attacks. The Warlord is a little short on chainable attacks, so more than most classes you'll rely and charges and breaks to soften up your opponents.
You have a variety of both, giving you many ways to close the distance with even the most agile enemies. The offset to this is that the Warlord uses up stamina very quickly, so time your moves wisely, or just turtle up and aim for the revenge-fuelled massacre.
