So a friend has a Gladiator Frostwyrm on an alliance DK and he wants to bring it over to our realm on horde-side, but he has a level 80 DK he wants to keep with all the Inscription recipes because he worked really really hard for them.
He asked what he should do because he wants to keep his Inscription but he wants the pretty mount (something I can totally get behind), and I was all like "Give the Inscription character to your wife with an account transfer?"
And he was all like "Cool! She'd like that! But we don't have the same last name, so I dunno if that'll work. :*("
And I was all like "Nuuuuuuuuuuuu!"
And my brother-in-law-in-law (I really need to find a shorter way to say that) was all like, "I think I heard you could have more than 1 DK on a realm/faction if you transfer. You can try it if the account transfer doesn't work."
And I was like, "Hey, I remember hearing that too! Lemme look for proof!"
So I dug around on the interwebs and found proof on two sites I can't actually link because they're all about WoW exploits and hacks and botting and cheating and bad stuff. But they had screenshots of valid, legal multiple DK transfers. I'll put up their proof photos for you so you can see I'm not just saying it, but no links because exploiting is super dumb.
Exploiting is Super Dumb
I want to emphasize this. The same friend who wants his Frostwyrm has known a lot of guys who've thought exploiting or hacking or botting were cool, and he told us that every single one of them eventually got permabanned every time.
And then he'd say I Told You So when they whined about losing their accounts.
He said it took a while for the bans to happen, but none of the guys he knew ever got away in the long run, and plenty of them would start up a new account and try to bot/exploit/hack all over again and then (always eventually) get banned again.
So, kids, do things the honest way. You might not get to brag about making 1 billion honor in a day, but at least you'll still have an account.
