People have already voted with their wallet and we see where the result is. If the armor system is so terrible, it wouldn't have this much player online at all time. The moment they give you the ability to mod the game, they have already given the minority to fix their own issues and they will only step in if the issue breaks the game for the majority of the player and their experience, like Lucky Charm and Reactive armor nerfs.
With that argument No Mans Sky was a perfect and unflawed game aswell.
D:OS2 gets heavily hyped without anykind of criticism like it happens pretty often, that is why many are jumping on the train and buy it on the fly. Also most people don't have really high standards or really bother to take a deep look into the mechanics. On the surface it looks and feels like a decent or even game I guess.
Also many sales happened during the kickstarter campaign coming from D:OS1 influence.
For me personalley D:OS2 is a hugh let down, not as bad as No Mans Sky but not that far either. Not solely because of the armor system, but because of all the stuff that adds up into a low depth RPG. And how less it feels like a successor from D:OS1 thanks to those countless changes.
With so many core mechanics changed at the same time, it is not surprising how broken it kind of tends to feel.
