Why is it leeching because someone wants to gather there? There are new gathering nodes there for a reason. Why is it required you go there and help fight. If someone wants to go and gather the whole time who are you to tell them they cant?

Leeching would be going in and just going afk while still rolling on all loot. Which is what's coming next as soon as these types of players find out they can. Then your going to have much bigger problems in there than someone gathering as intended.
