Nostalrius Begins - Quality wow vanilla realm (1.12)

You should add a feature to copy characters from one realm to another(i want to copy my lvl 23 mage from pvp realm because it lags too much to pve realm)

No.

If it lags too much just make a new character. Level 23 isn't high.

We've stated many times we will not copy characters from the pvp realm to the pve realm.
