Let's build a guide to Patricians- when to build, what to upgrade, and in what order?

Since this is a new and pretty unexplored area of the game, let's start comparing experiences and putting some tips together.

It seems like the biggest question jumping right in is what to do with your cashflow.

Is it best to start by...

• Saving up to build new trade posts?

• Upgrading existing Trade Posts?

• Upgrading your family palace?

• Upgrading your normal holdings, such as your capital city?

It's a lot to prioritize, on top of all of the normal considerations of CK2.

So far, I've been prioritizing building new Trade Posts above all else, followed by upgrading my family palace. Since these are both pretty expensive, it means I'm floating a lot of gold most of the time that I could be throwing into a lot of smaller upgrades.

What have you guys seen work well and/or end disastrously?
