I think this is happening because:
New players are being placed above where they should
and
Old players are being placed below where they should .

I think this is leading to a mixture of troll teams (maybe they just don't understand what's happening) playing teams who have their shit together more.

Things like people not getting on the payload to move it faster - over extending crazily, and not standing near the payload to stop it.

As a DVA main i'm pretty much dead if I don't have a few people around me shooting at people.
