This is not an explanation. It only rizes a question why they have kept so strictly to those rules.
Because they are the rules? Why would Larian pay WotC for the DnD usage and then not use it? Even if they did it does not follow that Larian would then make the game exactly as you want it.
Fighters, paladins, rangers, barbarians all get an extra attack at level 5. Not sure about monks.
Bards get an extra attack at level 6. Not sure about other classes.
All spellcasters get more spells and higher level at certain levels.
Why are you running with two fighters in your party? Two fighters, a rogue and a wizard is playable but not a great party for someone who is relatively new to this.
You only need to carry a torch until you get Isobel's blessing and the pixie gift and only one person needs to be carrying a torch anyway. Gale would b a good choice for carrying the torch as he doesn't do melee fighting.
I'm still struggling to understand how you can have explored everything yet be under levelled.
