You cant get free World of Warcraft forever but you can have a 10-day free trial, but after that its about £10 a month onwards.

If one is interested in trying out the MMORPG World of Warcraft, then a free trial is probably the best way to get started. The recommended method of doing this is to go directly to the WoW website and download the World of Warcraft Starter Edition.
The trial account isn't playable after the trial unless you convert it to a paid account.
