Well your only character is a Level 2 Gen 2 alt.
You also have a Level 30 Gen4 main that is a STF char and deleted...
So i went ahead and revived that one and unSTFed it.
Which means it's now Level 1 Gen4 and has all the items it had before and can level up again.
As both chars had the same name I added a second _ behind your alt's name.
I will also reset the role on both so you can select which one you actually want to use as your new main character but i didn't see any reason why you would use the gen2 over the gen4 especially as he still got his heirlooms.
If you select your main, the other char will permanently be marked as alt and can never become a main.
So trading the stuff from one char, then making the other your main is not an option just so you know
You will end up with an alt that has an heirloom but a lot of people have that "problem".
