Yeah, I never kick anyone either, but I don't love bringing randoms I don't know through something that is legitimately quite difficult/frustrating with a lot of the groups you end up with on the forums. Not having defender upgraded screams inexperienced in pve, I personally wouldn't kick them, I agree you should give everyone a chance but if I wasn't leader and they got kicked I would probably be happier if we got a more experienced player so I can see where the kicker is coming from. I don't get why you're hung up on the bubble thing, we both agree it isn't the issue in this case, they had two defenders anyway, we both agree that it is possible without a bubble, but there is a certain expectation that for end game content there is a strategy that will come to the forefront and will be used as a standard to make sure that we don't have to spend half an hour discussing strategy before each fight every week.
