When to get a 3rd General

At what point did you get a third general, or at what point do you think a 3rd general is useful?

Thanks.

when i started doing adventures

as soon as you can afford it!

get a bhg or a vet for quicker reinforcements

err.. asap.. the more the merrier :)

hm, somewhere level 25-28 when you start doing some suicides on your home Island, 1 general to keep alive and be able to do lootspots from your guild whenever they appear in your guild chat is a real nice thing to have.
The BHG(or equivalent) and Vet or MMA are more interesting for those lootspots and for reducing adventuring time, but they are not readily available for all at any time.
Especially guildies will (for the most) put up with the 15 minutes extra transport time for lootspotting with your simpel general.
