Only the invasion needs to be tested, so far I did not see any problems with them.
Let's see...
Publish 79 had 3 fixes published, one after it went live,
Publish 80 had 3 hot fixes and updates after it went live
Publish 81 took over 3 months to test and release, with 3 bug fixes and patches after it went live
Publish 82 was the simple Kings Collection publish with testing only over the weekend before it went live. Everyone said it was fine because there was nothing to test, only to find out there were other "fixes" included like the change to targeting and healing. Remember that one? No testing needed. OH - don't forget that months later people were still having trouble buying the Kings Collection from Origin.
I am glad that you haven't found any problems, but there was a reason that Origin and Izumo shards were added - to provide an extra week of debugging before going live to all shards. One week on TC, one week on Origin/Izumo before going live.
Is rushing this worth the risk of major bugs getting through unnoticed?
