Hello. Please, consider fixing group system asap. You crash alot when you are in/join a large group, you lag alot when you're in a group/someone join a group. Sometimes nobody is leader, we need to reform a group many times to get it to work. This happens since the betas, this is an important feature (as even in some solo stuff we need to group up because some unbalanced npcs can 3-hit-kill a full heavy - lol at this).
