Well... if you got 700h each under your belt I can say you've made a great buy. Every game has an "endgame" and sadly you can reach it quite fast in this one. Anyway, hope you find something else to drain your time.
Right. I dont regret to buyed the game. Rust WAS awesome. Now we need more content :)
OP, you simply play Rust too much.
Also:
These have no place in rust. Go back to Battlefield if you want this.
I dont say, that these are good things. BUT: they developed SO LONG on this! The could make other cool things instead of that!
