Hi Laz Man, I did not follow all the discussion on the Steam forum about the topic of expoits. One thing which eyestruck me, nonetheless, was the discussion that they were saying the developers want to make driving the horde away (on bloodmoons) impossible. I do not find that idea good. On my server we have a base at bedrock and two killboxes. The first one (killbox) was a neat design (which focused on blade traps) which I invented myself was working but after every bloodmoon we were almost two days busy, repairing it to ready status again. Then you had a few days to loot and have fun and then the next blood moon was in front of your door and you needed another day to prepare successfully for it. More than half of the play time was centered about those blood moons, which was okay for a while, but was getting annoying.
So I checked some videos on YT to get a more efficient design which I did built. Nonetheless I need to have 2/5 of the week for that blood moon (although the blood moon ITSELF is fun!), one day to prepare and one day to check for damage, repair and refill. In the long run, this annoyed me (and us) and, from time to time, we chose to drive away when we were quite busy, instead of wasting hours of playing time only because we were forced to, by not driving away.
So, the purpose would be to make EVERY base, no matter how much exploits it uses, difficult to defend, ON THOSE FEW bloodmoons which were designed to break your style of base (e.g. bedrock underground base -> lots of digging zombies). On other blood moons, you could still benefit from the "exploits" of your specialized base (ignoring airbased bloodmoons and bloodmoons without specialized diggers). So you would not need to spent every week half of your time for repairing stuff...
So, you may say, why not change the game settings to blood moon frequency only every 14 days. And I would answer: the point is, that you have to work very hard, until you manage to build a base which does work so effective, so you can ignore half of the blood moons.
And I think it would add more layers of game styles to bases and players.
Aside from some work for the devs, I guess the game would benefit VASTLY from it.
---------------------
If you would take away those different kinds of raids from Rimworld, it would get bland and dull very fast, because it would be too easy to beat the game.
So, I say: Make the game even more varied to give even more longplay to the hardcore fans. Possibly by making specialized blood moons a feature not for the first few blood moons, but the more days your game has. And of course, it should be adjustable by server settings (and you should be able to turn "specialized bloodmoons" off).
