Leveling a Warlock was the most exiting of all the other classes. If you like a range DPS class with cloth wearing, than rolling a Warlock is excellent idea. You will see how self-sufficient this class is. It is also a very powerful PvP class. So in the process of leveling you will be very very rarely be killed from the opposite faction (if playing on PvP server).
Leveling a Warlock – Which talent tree is the best for leveling?
First of all, I really don’t recommend leveling as Destruction. This tree indeed has very good damage output, but lacks of mana efficiency. You can burn the enemy down very quickly, but you often run out of mana after 3 or 4 mobs. So the downtime is big so with this build you level a Warlock in the slowest way.
Let’s take a look a bit at Demonology talent tree. This talent tree is known as utility DPS build. Your pets (or minions, whatever you want to call them) become very powerful. We can compare this to hunter’s Beast Mastery where also boosts their pets. For leveling a warlock, this is a good tree if you want to level fast and in the “calm” way. You just sent your pet at your enemies (at late levels Felguard) and they do their job. As I said: If you are a person that doesn’t want to have a lot of action and also want to level fast and efficient, then choose this Demonology tree.
But If you want action and the fastest Warlock leveling (if played properly of course), then read on. This you will get if you choose Affliction talent build. This was my leveling build and I can honestly say that I if had to level a Warlock again I would choose the same. With Affliction talents you boost your DoTs (damage over time spells). With talents “Improved Life Tap”, “Soul Siphon” an “Siphon Life” you will become mana/health battery. Your downtime for eating and drinking is zero! When it comes to killing the enemies: Have the Voidwalker beside you, DoT as many mobs as you can with Corruption and Curse of Agony. Keep in mind that more mobs you DoT with Corruption, more health you regenerate. You see the point? Then use Sacrifice (Voidwalker’s Skill) to shield yourself in critical situations and wait for the mobs to burn down. With this technique you can kill up to 10 or more mobs at a time. And this is why leveling a Warlock is so fast.
Leveling a Warlock – Questing?
Absolutely! Questing is the fastest way of getting XPs (experience points). But be aware of some fact. There are tons of quests designed just to slow you down. They reward you with very little XP and take you ages to complete them.
