Not Updated For Current Season
Let me start by saying I learned to play WW from Dewo's guide and if you have not looked at it and read it to its entirety stop reading go look at his which can be found here.
What this guide offers that differs from Dewo's is mid/late game staying power and imo better 1v2 style as well as being able to survive if focused. On the negative end you will not just flatten 1 person outright and the mid game is a little slower. Now some people take a look at this and probably think it will not work however I suggest you at least give it a chance.
Another huge advantage to this guide is the ability to solo baron at level 15 (14 if you have stinger at this point). Thats right at level 15 you go solo the baron for your team.
Jungle early Jungle/Gank middle and at the end. The real skill is managing to jungle while pushing/ganking in the mid game b4 you have stinger. Dont fully commit to standing infront of a tower letting your minions rush in go jungle during that. Make sure you always kill the dragon/baron for your team.
I could try and explain the intricacies of WW however it would be a copy and paste from Dewos if your reading this you want to try something a little different and its basically the item build. Ult someone use Q often picking off their carries by the time you have an Atmas/Bloodrazor you should not have any problems in team fights.
The one thing I will suggest differently is getting Bloodrazor before your Sunfires depending on the team how early ganking has begun etc. If you have enough gold and can get away with it go bloodrazor but remember your gonna want atleast 1 Sunfire to do baron and again this is just my opinion but during a push if you can go solo baron early its really a nice advantage even if its just preventing them from getting it.
