Just stop and think for a second, you have it the wrong way around and so does 99% of the player base which is why they are changing XP in the next build because builders like me are taking advantage of this loophole.
The game punishes people who like combat and rewards builders.
You get a low amount of XP for not killing anything which means you can keep your gamescore very low and build at your leisure knowing that the bloodmoon horde will pose very little danger. Iron tools & weapons which are easily looted outside of POI's can be repaired without a perk. Finding a forge (traders or gas station) means you can craft iron spikes, iron bars, truss frames and all other types of iron, again without needing perks.
Conversely the player who likes combat and clearing POI's is "rewarded" with higher XP. That player has a high gamescore, very high level, but he/she has been so busy power levelling they haven't build much to help with the base defence.....and then they come on these forums and cry that it is "impossible" to defend your base or they post their cheese AI exploiting base designs thinking they are awesome because their power levelling has "rewarded" them with a very strong BM horde.
This is my base after 21 day BM (singleplayer, default settings), I am level 11. I didn't even use my guns, just wiped them with my compound bow. Like I said though, they are buffing non combat XP because people just cried like a bunch of sheep without thinking that builders had it good in A17, REAL good. GG.
