ahh so the 3 fort is to deter those below 100 and above will likely chose other targets anyway?

Yep, you will still get attacks at fort 3 but not as much only 1 and very rarely 2 attacks per claim window. At 4 fort and below 100 rating you rarely recieve attacks.

hmm yeah I was thinking of keeping fort at 3 and upgrading faith a lot after 100 rating..

figure most above 100 won't go for the 1 part minimum anyway and faith taking a large cut could make others more favorable target, might need to go to 4 if low ratings keep attacking
