At Duel launch, Kate timed out frequently. It was particularly painful for Smartphone users waiting 3 Minutes and unable to move on in their match.
But Kate's A.I. continues to improve. By that I mean she trolls like the worst players. Sadly all the fun and extra matches we used to complete missions will be removed soon. Too bad, Duel & Kate was a quick way to spend an hour on UR if you didn't feel like playing ELO.
