Invasions should be removed and replaced with more aggressive higher mob counts the further out you go. I'm sick and tired of having a troll completely wreck my base in the very middle of the entire map, in the Meadows, when i'm trying to go to the bathroom, I would rather have my base be threatened from the biome itself and not some rng bullcrap interaction. (yes i am well aware that killing the bosses/placing the heads whatever, will increase the invasion levels)
What's the point of building a tower in the Meadows, if some troll can wreck the foundation? Seriously, stupid decisions.

So basically the only option to avoid that is to build on an island, and i hate islands, i hate this game when invasions happen.
