I got a questions, it is if i am W/As ( Warrior/Assassin ) and i will go back to Kryta, or the first world. Can i so use my assassin skills or what ? Or i can't travel back to Kryta because i am Assassin as my Second Profession
If you link your accounts, which you will need to do if you wish to travel to Kryta with an assasin secondary, you can just use your skills as if it were one of the core classes.
So yes, you can use the assasin skills and travel to Kryta.
