My old character.

[DontDieNearMe]

Before the hijack , I had a shadow priest , Errelf, in Frostwolf, when it was Cata. Would it be able to get that character in a Cata server , i mean everything with that character - achievements , titles, items ?

Short answer : No.

If you came in the 7 months there were a lot of things to at least kinda recover for it, coins insta level ups etc..

Molten staff created some sort of ways to "recover" things, as bunch of free coins and points, 5 lvl ups, 3 profs... Which were somehow a poor act for players with many chars, but well, less is nothing. Those tools and methods expired long ago, anyways, so I'm afraid you have nothing left here : /
