With altering your playstyle, you mean logging off, because that's the only viable option as far as I can see.
As for the things they want to fix, isn't it possible to disable something right now, so that it at least isn't causing problems?
Not at all.
You see it as black and white, or two diametrically opposed viewpoints.
One is "make a base and get overrun and thence log in/out depending on if a horde comes or not."
Players choose to remain in a fixed position so they can come right to them.
I suggest that you could maybe not remain static so once they fixate upon that point you can avoid harm.
When the horde spawns it comes to the spot you were at when it spawned...it isn't tracking you as it comes.
So just do something other than hunker down at a fixed location.
