The bigger question I have is whether or not this will result in Blizzard fixing the number one problem with finding games right now, which is caused by each region having been sharded into sub-regions where each half (sub-region) is unable to see the other half’s games. It’s a really broken system currently and if left in place, no amount of database fixes will make players happy when finding games is difficult to impossible.
As for combining the database stress test with content testing on the PTR, that’s a tremendously terribad idea as it spreads resources too thin for either test. You want the focus to be on one issue at a time, not multiple issues. The number one rule of troubleshooting and/or testing is to narrow the number of variables to as few as possible, and stacking database testing with content testing does the exact opposite and would result in a vastly inferior product for players. It also produces additional crunch, which is never good for quality production.
