Thieves now have specialization like many other classes here do. There are five different paths to choose from, with each path having far different skills and playing styles than the others. You are allocated a certain amount of 'thief points' that allow you to choose your paths: you can choose to specialize in one path fully (and possibly some beginning skills from other paths) or split up your allocation into several different paths.

That said, in your case, you went from Tir-Talath, which teaches the thug path to Galadon, which teaches the Pickpocket path. The following is a snippet from the helpfile on 'thief paths' (which you can access either in game or in the text box in the left frame of this website) which lists the major guilds and what style they teach.
