My alt has 4 fisher retainers... (soon my 2nd alt will as well)

1) stupid easy to get fisher to cap (don’t need to clear any major amount of storyline)
2) constant source of income via 18h ventures (Allagans coins, occasional minions sell well)
3) all retainers on same job = only 1 class I need to level

Don’t necessarily recommend it on your main character, but on alts? Easy money.
