Hey guys 
i want to share a fast way to to get your Lockpicking to 225.
Redridge - Alther’s Mill : 1 to 90
Redridge - Lake Everstill : 90 - 150
Desolace - Ethel Rethor : 150 - 200 (225 if you are patient) ( in video i said 190 instead of 200 which was my bad sorry ^^ )
If not… Pickpocket mobs in: Badlands - Angor Fortress or Pirates in Tanaris ( they will give you Sturdy Junkbox, to skill up from 200 to 225) after that you will be able to open all of those sweet chest that every1 is looking rogue to do it and get some tips 
Oh btw dont forget ( elixir of water breathing ) it will help you a lot
GL my friends! <3
