Since you tagged this as pvp, the only solution is to blow it up, or use a trebuchet. Blocking obelisks and public map rooms in no way is blocking content of the game…you got legs, you can walk. While Ill agree its a less then noble strategy, on the pvp servers there are ways to counter it.
Why should i use resc for something i dont get anything out from ? There are some low lvl folks that have a hard time to become strong. I dont want to lose some nice ppl bec of this behav. Plus there are some rules in official server, u could read them.
Blocking is part of the game. But so is spamming sandstone wherever you want. Just get bounty oils, put it on blood pick, then harvest 2000 sandstone. Start filling in what ever you want. You know, it is part of the game. They can blow it if they don’t like it.
If they don;t blow it up, do another 2000. Kill the server with them. Because apparently that is the end game of official PVP servers.
