First of all thanks for the fast reply

I have already started my Rogue and have no desire to start over from scratch, thus I will be paying the 20€ it costs to transfer one of my 70's. Keep in mind that the 70 might also be used to boost other alts in the future. However, I am still pondering if Hunter is the best option. For me it's not just a question of getting the character to 70 in a hurry, but also the viability of doing some odd PvP at 70 and possibly farming elites. For that I think the Feral Druid would be a better option, would it not?

I know most people here take multi-boxing further, but I do not have the desire to replace my current playstyle with multi-boxing, but more using it as a supplement - eg. boosting alts through instances, having extra character slots and so on.
