Be sure that you know where you're talking about before you defend Sam. He has been offered a lot of help, but didn't take it. Now after 26 lvls he started a Quest which all other boxers would skip because the mobs you have to kill are under water. Nice? I think not. Now he finally managed to do a Quest and he's all great? come on. Then Prepared must be a god.

Lvling a character in wow just takes time. If you think and rush through quests, you're just faster. Having 26 characters will make a lot things a lot more annoying and time consuming, but why would it be harder?

It would be harder to do it fast and smoothly, yes. But with his endless mobfarming he isn't really going fast.
