Hmm I thought the boxes were used for rep swell right?
Okay.. i'll start from scratch
What kind of income do you get from this;
Depends on your server, you'll be farming boxes.. and selling them to people who are doing the ravenholdt reputation farming for the insane title.
30-40 copper each time you pickpocket, it's not worth it if you are doing it for the "pure" gold. They are sold for 15-20g on my realm, since i ran out of buyers.. i did however sell a ton to people for 25g + ...
What can you get from the boxes? ;
It has a small chance (0.01% i think) to drop a 1h sword that is used for transmogrificationing your weapons to make them look like firey swords (check botanists first post, there's a picture of a rogue using the transmog.) - You can either use it yourself, (BoE) or choose to sell it on the AH for X amount of gold.. it sells for 100k on average.
What can you do with them?;
As explained above, you can turn in 5 boxes (opened or closed, doesn't matter) for reputation, people will need 1200-1500 boxes depening on them having a lvl 25 guild, and further rep + gains.
Is it a good profile? ;
Yes, it is. Works flawlessly, however.. it all depends on you being able to find buyers.. so that's why i suggest getting around 4-5 buyers before you start farming them.
Is it the best pickpocketing profile?
deffinatly not, atleast that's my opinion.. you should be able to find profiles that would gain you alot more gold using that kind of farming ^^
Post again if you have any questions, how to use it etc. is written in the first post by Botanist - so that should be easily done.
