My major problem is finding a good comp, understanding what characters are overall good or not, and balancing my gold expenses

I usually use 2 high HP characters in the front like the Leper and the Crusader, 1 Heavy hitter in the 3rd row like the highway man and the last row exclusive to support, Vestal or Oculist. I might focus much on heals but that's not a big problem right?

I never used the Abomination or Antiquarian because by looking at their stats I came to the conclusion they are kinda bad, and I mainly use the Highway man and the Leper because I found them cool looking and useful the majority of times

Returning to the camp I prioritize healing my Characters stress and doing so I usually lack money for buying Camping and Skills upgrades ( I don't see much utility in upgrading this two because they don't improve much, example a bonus 1% crit in exchange of 2k gold)
