When we had Spiral Showcase, a few times I tried teaming up in Polaris and that automatically gave the 10 minute penalty, and to make it even worse, the penalty did not count down when switching characters.
Another thing with the team up is, some areas have an extra long loading time (Lord Nightshade is one) and this can be detrimental if it loads fast for one player who decides to win it before others can load.
