How would this laptop hold up playing World of Warcraft?

I'd say that laptop is overqualified to play World of Warcraft. It's a pretty old game, that laptop will run it smoothly for sure. I'm not sure about its cooling properties though so I cannot ensure that it may not overheat at some point (since mine does sometimes while playing pc games). So get a cooler as well since that is definitely a must when playing games on a non-gaming computer.
