There are many classes changed in Wow, what are the easier classes for players?
Well, I think paladins should be one of the easiest classes to level up in Wow MOP 5.0. It is a defensive focused class that can heal, wear highest class of armor and gets several types of damage shields. They become very self-sufficient when they reach higher levels as their retribution abilities regenerate health and mana. They are also a hybrid class that allows the person to choose any of the three roles of tank, DPS or healer which can make finding groups to level with a lot easier.
In addition, hunter is known as the most common choice for leveling up easily. There are tons of people who have leveled to 60 in around 4 days and 20 hours as a hunter in wow. Here are some reasons:
Low dependence of gear to do damage: Hunter can do decent damage even with crappy gear.
Pet class: A pet will help you fight against enemies for it can hold the monsters’ attention while you're killing them.
Ranged DPS: You don't have to be teeth to teeth with the enemies. Hunter is specializing in ranged damage dealt.
Built-in regen mechanism: You're able to regen while doing still some DPS and farming WOW Pandaria gold, and you're pet is able to DPS as normal while you auto regen.
However, I think the easiest way to level up is to buy world of warcraft accounts directly. Find a professional game support website like farmer100.com, which can provide you cheap wow account, power-leveling and other customer service. It is also convenient for you to sell world of warcraft account, if you lose interest or you want to change other account to experience wow.
