Hello there, I find my game quite easy with my current party even on hard difficulty. The only time some of my chars died was when Rex did his AOE fire spell in first turn. On the second try I completely wrecked him though.
I was looking for a bigger chalenge so I wonder if the game gets harder after that fight or if I should make another, more challenging characters.
My current party consist of rogue/witchcraft hybrid, fire/geo mage, Jahan and Madera. But I'm tempted to try out two lone wolfs, probably warrior/air hybrid and ranger/hydro or rogue/witchraft character. I think that playing with just two characters can be pretty challenging, even though lone wolf make them considerably stronger.
