It would be great if it would be possible to leave the tribe more often, as it always was in the round settings.
In the last time there are often big groups playing and then we always have the problem, that we can not support each other.
For example we played together with a sum of 5 ppl at a 3 tribe limit and then we got attacks from 9 ppl, we wasnt able to support each other.
I think outside support hasnt something to do with, as HotLikeDat said, that there pure numbers wins, other than skill.
What has it to do with skill, when 9 ppl play together and smaller groups can not support each other because of outside support is disabled.
So there is even more less chance for smaller groups.
Maybe there should be a fair balance of rounds with leaving tribe and outside support and rounds where leaving tribe is not possible.
As HotLikeDat said, 95% is way to much, in my opinion, maybe 50 / 50 or so.
