There is currently a 2-minute queue time addition to play against a team you just played against (so, 2 minutes plus normal queue time to be matched against them). This time value was 5 minutes when 3.2 was first released, but was lowered to 2 minutes in a hotfix last Friday.

The purpose of the time addition is to make it less likely that an average team doing arena games for a night isn't likely to run across the same team in many of their games for the session. We'll continue to tune the system to make sure that it doesn't feel like too much of a nuisance when there simply aren't other teams within a reasonable rating range to play against.
