Yes, what Jones76 said: better get used to it. But also know that there are many ways to approach a seemingly impossible battle. Make use of potions. Make use of the environment. Get the enemy bunched together somewhere, spread out your party. For example, Dror and his minions can be toast with only one shot, or one throw of a burning candle, if you take note of the abundance of explosive and flammable barrels in the goblin compound. In general: try to be creative, try radically different ways of solving a problem. Discovering tactics for yourself can be very gratifying.
