People use it since closed beta and it's working well.
I really don't like the time bank system where a match takes an hour or so, just because you have to play the same map over and over again.

We've made a lot of improvements to reduce match time in Season 2. Lots of little changes that should add up to make a big difference. We feel like Time Bank is a system that has a lot of the same advantages Stopwatch does while retaining more of the natural drama that's built into the core gameplay of Overwatch. These new changes bring us even closer to Stopwatch, in many ways.

And that's really odd that you're seeing hour long Time Bank matches. Our stats show that the average Time Bank match in Season 1 lasted 16.37 minutes.
