Bungie seriously need to implement a punishment for kicking teammates for no reason before an activity ends. I recently was kicked before the end of a grandmaster excision run. As you can understand, i was annoyed that someone can just ruin your night with a click of a button. I understand that it is hard for bungie to know what is a deserved kick, but there must be someway to detect when it is unreasonable and unwarranted. This is a genuine issue that bungie has to address.
