Hey Xenius.
If someone were to invite you you can create a new WoW and level together, after doing that you can transfer those new chars to your main account as long as they are both on the same bnet account or both bnet accounts have the same last name.
Nowdays the game is only Battle for Azeroth that you have to buy and with just gametime you can play so basicly all accounts that arent BFA are at least fully upgraded up to Legion.
I would love to RAF you, send me a message if you are interested!
Currently I'm playing on Dreanor Horde but I'd love to play Alliance too if that's your plan.
