WoW Token question

[MiRai]

Now my question is, if I get myself 5 accs and level up a team of 5 Druids, Hunter or DK, would it be possible to make enough gold per month to get new gametime for all the accounts via tokens ?

Yes.

I read some threads in this forum and people talked about mining and herbing but I wonder how that would be more effective to do with 5 accounts instead of 1 since herbs and ore isnt unique for every player.

Nodes can be shared with up to 10 players.
