Gloomhaven 1st E house rules and tips?

Hey guys, I am about to start my first go into Gloomhaven. I have played some JotL so not completely new. I was wondering if anyone had any house rules or tips that they found improved the experience? Im a forever DM for DnD and I love learning about how other people change to game to bring a little extra, so I figure there has to be some things like that for GH from experienced players.

Thanks for the help!
