That is one major factor in how raters get high rates is by stacking. It just makes sense for them to join the team that they can rape the other team easiest. Most of time if raters can't get in on the strong team they will just disconnect. Raider is guilty sometimes, but mostly he is just so good it doesn't matter what team he joins and the nuthuggers join his team instead of going against him.
9 time out of 10 probably you can join Silent XPS or Hardcore, and the teams usually are stacked. Frustrating but nothing can be done most of the time unless a lvl 12 or higher joins. So we have to just sit and be raped until autoshuffle.
