The x10 xp gain is to help leveling so you can test any class at any level and not take forever leveling.

They do port the official data to the experimental server but how often they do that all depends on what is being worked on. I'm sure the structure of the database is changing all the time and putting in the effort to keep the data mappings is not practical. For the stress testing from time to time there is a server message to go to the experimental server granted it is in Spanish but it is not hard to guess what it means. The hard part is guessing what they need help testing. Then again most of the players speak Spanish so I understand why that is.
