Gloomhaven is intense!

I have played many "hex strategy" games ex. XCOM, Rome:Expeditions, For The King where i have benen able to play at The higher difficulties from The getgo, but GH was not easy on you, played The first tutorial but just wanted to get started, and boy did i get humbled. Played w Spellcaster and Brute and got rolled on Hard difficulty (Burned too many cards and did not optimize turns), After losing a few scenarios i chose to switch upp my gameplay and chose Scoundrel and Cragheart and switched to normal and started understanding The game some more, and its unforgiving but very fun i must say, i have only retired two mercs, but this game feels promising! Definitively a new and interesting experience, and it really tickles my tactical brain and I love it! Anything i should be aware about in this game good/bad?
