Whenever there's 2 or more players difference between teams, teams would balance automatically by randomly choosing from the team which has a big advantage to switch to another team.
I couldn't care less if it's a flagger who gets picked or anything, because it is his own fault for not balancing teams and not looking around if teams are balanced or not.
The current team balancer-feature (which is a server-side option, I assume) just won't do it. It's too easily exploitable to make even so teams unbalanced.
Is that so hard to create? If it is, what makes it so hard? This would be a server side-option as well.
And no, I couldn't find another topic regarding this topic from this forum. There might be one but it's already buried so deep so it's as much as worthless to bump it.
