Okay people: listen.
Obviously, some people aren't prepared for the change. Most people on the forums have heard about the Chest Update and have been ready for it... heck: excited for it, for a long while. Meanwhile the serverside people are happily playing their maximized-for-pvp survival games without a clue of the looming changes.
This change is pretty drastic to gameplay: chest routes are totaled, teams are slightly more OP (many hands make light work), and the deathmatch isn't stacked to the brim with iron armor and diamonds. Surviving is now part of gameplay once again. PvP is still major, but it is less of the focal point, now sharing the limelight with starvation, poor armament, and ill-equipping. Survival is what will make MCSG more fun again. It's more of a challenge, more of a goal. Especially for people who were 'too good', this update is a life saver of our declining enjoyment.
You'll survive the update, and you'll enjoy struggling to survive in the games.
May the odds be ever in your favor.
