Some Question's concerning Heroes

Hi,

Sorry if these have been answered elsewhere.. I tried searching and still not sure..

1. Can you only ever have 3 hero's at a time?
2. If you have 3 hero's already does this mean you'll never get the chance to get another hero?
3. If you can swap hero's.. if you swap a hero you already have for another hero, do you permanently loose access to the hero you swap out?
4. Or can you come back at some point and swap them back into your group/party/hero-list?
5. If you can swap hero's in an out, where do the hero's you've swapped out go? Back where you found them or some centralized point?

Thanx in advance for any answer's

1) Yes, I believe so
2) No, you can still get Heroes after getting your 3rd one.
3) No again, they will be read for you with the last build used.
4) Just pop into a town or outpost to switch.
5) When you get your 1st Hero, an "Add a Hero" dropdown will appear in the party window.

You can have access of up to 12 heros at once, but you can only have 3 of your own heros with you in your party. Once you swap out heros, you still have access to the one(s) you swaped out. When you swap a hero out, then you can put them back in at any town/outpost.
