Hello! Welcome to the game and the community! :] This isn't really the right forum to be posting this, as this is the modding area, for those making mods for the game!
A better place to peek would be
here! Balancing is a bit wonky, if you want to be really strong, two lonewolves with warfare based stats, some necromancy and stuff and you're good to go. I played my first playthrough with a "World of warcraft party", and it was manageable, but tanking and healing isn't as much of a thing (unfortunately) as pure dps and strategically picking off enemies.
But half the fun is just diving into the sandbox, try, experiment and explore. Enjoy the adventure :]
