Hey !
I have found a new way to get more than 2 Tradeskills.
Here is what u do:
1.Get Any skill u want
2.You might wanna level them u'll be getting +skill from the GM
3.Make a ticket Explaining ur Proffesion Window Exploded or that u "Accadentaly" unlearned the wronk Skill and wanna get it restored
4.Wait for a GM to come He will most Likely add u the Tradeskill u lost and than u can learn another 2
5.Profit & Enjoy
