I see boosted as for people who just want to PvP, and not grind, new players that don't know what the best harvest methods are, and lazy or solo players who don't care about people opinions of what survival is, and just want to have fun playing.
The boosted servers have a lot of turn around, and corruption, so you need the boosts to constantly rebuild, but the boost causes the corruption, so its a catch 22.
I don't like boosted. Were at x5, and people already get way too much C4 way too fast, but to each their own. I like having a stable map over everything on day one.
