There's no doubt about it, Heirloom items are an alt's best friend. The powerful weapons and armor, level scaling, and experience bonuses are simply too valuable to pass up. Heirloom items can literally cut down on hours of play time, since you'll be killing and questing quicker and earning up to 25% more experience per kill or quest. But how do you get heirloom items? There are 3 methods to acquiring these coveted heirlooms.
The first method is PvP, or buying Heirloom items with Honor points in Wintergrasp. This is one of the cheapest methods in terms of gold and possibly the safest because you will not lose any money due to repair bills in PvP. However, it is the least reliable, and you can get them at earlier levels. It takes some grinding in Battlegrounds and Arenas, and the amount of points you earn is totally dependant on whether you win or lose, and also on your number of honorable kills. In addition, these are PvP heirloom items, while boasting nice stats, and scaling with level, provide resilience instead of more useful leveling stats like crit or hit. The next two methods will cover how to acquire the kind of Heirloom items that are best for leveling.
The next method is to run Heroic dungeons. This is something you should be doing anyway. You want to run Heroics to level up your gear and get ready for raiding. As an added bonus, while you're defeating Heroic bosses, you will also be receiving Justice Points. These Justice Points can be traded in for Heirlooms. However, you will have to choose between your alternate characters and your main... These same Justice Points can also be used for high quality rare items that you may want to use on your own character. In fact, BoA items will cost almost twice as much as the rare blues gear that you may want to use on your main character. So you may be wondering if there is another way to get WoW heirloom items.
If you want to know how to get WoW heirloom items, then the answer is simple... Complete your daily quests. Return to Northrend and complete all of the Argent Tournament Dailies. After a little practice you can have all of them done in an hour, and at 17 Champion's Seals per day, you can get one BoA item within 5 days. In just under 2 weeks, you can have your shoulders, chest guard, and 2-handed weapon to hack and slash through all the game's content. If you run Heroics, at 70 Justice Points per boss, you would have to kill about 126 Heroic bosses in Cataclysm to earn enough Justice Points for the same gear. Now tell me which method to get WoW heirloom items is more efficient. It's pretty simple to see that Argent Tournament Daily Quests are hands down, the easiest way to get WoW Heirloom items.
So, if you're starting an alt, then you will want these Heirloom items to make the most of your leveling process. If you have a good plan, you can complete your Daily Quests for the Argent Tournament in under 30 minutes.
