You keep saying the game is too easy, but then you say skill drain is too punishing and you die too much. So which is it? If you don't like taming animals and building but only killing stuff you should play something else really. I can think of several titles to recommend. The game is really what you make of it.

You don't like all the useless greydarve mobs interrupting you. Then build a carpet of workbenches. Problem solved. You can so this in your base and around your mines or whatever. Sometimes they get taken out if outside you base. By that time, the mine is played out anyway.

Myself, I need all those greydwarve. I have lanterns all over mutiple bases. Need the resin they drop. Make lemons out of lemonade eh.
