Again. This is early access. In the current build, literally everything is broken - warriors, rogues, rangers, and mages. The final game will certainly be harder, you can count on that. That, and it will have a tactician mode if you truly crave a challenge. The current mess of balance is not because of a deterministic system; it is because Rage is broken, warriors are doing too much damage, snipe is overpowered and CC doesn't have many counters ingame at the moment. But this moment is by no means representative of the experience Larian wants to give us. Trust me on this.
