Titles? You want titles? Just try to avoid earning them. You can't! Honestly don't worry about the undying title. We tend to mock people who put a big emphasis on it. Ooh, so you're "Honoria Who Runs From Danger" /snicker.
You'll earn titles for killing X amount of a certain type of creature, titles for completing X amounts of quests in an area, titles for defeating specific mobs, titles for completing crafting tiers. You'll end up with many to choose from.
And yes, I do go for the titles one earns from receiving certain emotes. One of my favorite titles I like to sport now and then is Yanari the Dull. I also have Yanari the Harassed and Yanari, Pie Eating Champion, among others.
