The pros about wukong is later in game he gets really tanky and you can destroy everyone. Be careful in the beggining he needs to be with good champions to get a lot of kills. Well not a lot, a lot. When you finish your build you can go one on one with another champ. I think its really fun to go one on one.

The con about wukong is no matter how many people are there are some champions that get another really good build that has attack and can kill wukong.

For dominion, get prospectors blade http://edge4.mobafire.com/images/item/prospectors-blade.gif then berserkers greaves http://edge4.mobafire.com/images/item/berserkers-greaves.gif. After that get vampiric scepter http://edge4.mobafire.com/images/item/vampiric-scepter.gif and B.F. Sword http://edge4.mobafire.com/images/item/b-f-sword.gif. After that upgrade the vampiric scepter and B.F. sword to Sanguine Blade http://edge4.mobafire.com/images/item/sanguine-blade.gif and then 3 giants belt http://edge4.mobafire.com/images/item/giants-belt.gifhttp://edge4.mobafire.com/images/item/giants-belt.gif http://edge4.mobafire.com/images/item/giants-belt.gif. Upgrade the giant belts to 3 frozen mallets http://edge4.mobafire.com/images/item/frozen-mallet.gif http://edge4.mobafire.com/images/item/frozen-mallet.gif http://edge4.mobafire.com/images/item/frozen-mallet.gif

For Classic game, i recommend getting doran's blade http://edge4.mobafire.com/images/item/dorans-blade.gif then berserker's greave http://edge4.mobafire.com/images/item/berserkers-greaves.gif then zeal http://edge4.mobafire.com/images/item/zeal.gif then 3 giants belt http://edge4.mobafire.com/images/item/giants-belt.gif, http://edge4.mobafire.com/images/item/giants-belt.gif ,
http://edge4.mobafire.com/images/item/giants-belt.gif.
After that upgrade two of the giants belt to warmogs armor
http://edge4.mobafire.com/images/item/warmogs-armor.gif. Then sunfire cape http://edge4.mobafire.com/images/item/sunfire-cape.gif or one more warmogs armor http://edge4.mobafire.com/images/item/warmogs-armor.gif.

Masteries are basically builds up to strength. These items could really help you do some real hard attacks.

Runes. I really dont have any. But choose what you want that you are lacking in.

These are the builds for wukong in classic and dominion
