PvP through Roulette is always longer because you can be placed in a dead que with some newbie who wanted to try Secure for the first time. Also it may be bugged, sometimes after 30 minutes I reset Roulette (which has in-progress checked), que directly to Shatter and get an instant in-progress pop. The best time for Roulette is if you get a few Shatter matches back to back, then Roulette can be an almost instant pop for the next match.
