Minimum dominion?

[Micah]

I took 5 with an imprisoned bless chassis in RAND, it was pretty tight and took a lot of priest MM (I built a fortless temple to buy indie priests from to preach for scales) but it worked out. A nice benefit from the priest building was being able to dom-kill mictlan when his last army of nasty double blessed jags was running amok around my provinces, since I had a lot of targeted dominion spread. I'd probably try to find some points elsewhere to have a bit more if I did it again, and wouldn't go under it, but I'd say it proves that 5 isn't under a minimum.
