i understand your feelings it is very frustrating but actually like most things you , surprisingly get the hang of it after some game time and get used to all the pit falls but still get wiped but not to badly.
So don't give up! You are frustrated at the moment so just have a break for a day or 2 and you will be surprised how you progress and learn to avoid the loss of experience points.
You will unfortunately get really frustrated with the death skitas and goblins they are one hit wonders but you find it is ok once you have a few successes and with really good armour, wolf armour is when it gets good and good weapons you find it ok .
You just get used to it.
Good luck old boy are you old or something with a funny - i am giggling , name like you have.
