World transfer, farm or delete characters?
The Birthday Gifts are pretty nice nowadays.
For some, Gold is not hard to attain, but for others….
It’s really up to you; you can try farming for Gold for awhile, and see how it goes. At least wait until the 5th Birthday Gift; it’s only a couple of weeks.
Oh, and make sure your friends’ Server is not Full; check after weekly resets or match-ups.
Good luck.
