…is not even a word, so i hope it doesn’t say that 
Sabotage, is what I assume most people would call “griefing”.
i’d report that under cheating.
anyone can leave a dungeon any time they want.
they don’t need permission or an excuse.
nor will they ever be penalized for it.
report afk.
Hi there, hello.
Game sabotage is when I’m in pvp mode and the player I’m trying to kill won’t let me kill him. Or when another player try’s to kill me and i don’t win. That’s game sabotage. lol
Yes I sadly recall that too well, was insufferable at times as not all of them would say a thing they’d just go afk and sit there till kicked. I recall one I ran into griping about getting that tolvir city dungeon and he just groaned and sat there, healer was having a fit until a DPS druid went tank spec and did the tank’s job then we just booted the old tank and pressed on.
No, no it is not. There is no rule anywhere saying you are held hostage in a dungeon. You just cannot be rude when you leave.
Now if you run into the dungeon, pull a bunch of stuff, flip the group the bird, then leave, then yes, this would be for that.
Also another good example, trying to kill a big mob, some tank comes and taunts it repeatedly, running away with it to reset it. That is gameplay sabotage as well.
Sounds like going to a low level enemy town with Warmode off, and keeping the quest givers, vendors, and flight masters dead. You would effectively stop people from progressing.
But back before everyone put their feelings on a silk pillow on their shoulders, we would call out in world defense, and the max level PvP kings would come in and save the day. And that’s when this game was fun.
These are excellent examples! Just like Jofbitanu said, the problem isn’t about simply leaving.
