To all who have experienced frustrations, traumas, withdrawal symptoms, outbursts from the recent spate of bugs, let's take a step back and take a deep breath. There are quite a number of major changes to CO over the last few months. We are not talking about new APs or CSs but fundamental game mechanic changes and a new open map event. When the fundamental mechanics of a game is changed, the impact runs through the land. Even though the major shockwaves are over, minor tremors still continue to ripple and are felt in various areas.
While grappling with the less severe bugs popping up, the devs are also trying to introduce new mechanics (like stealth and sneak) and major event like the invasion. Unfortunately, such new introductions also require quite a bit of considerations and coding. There are bound to be bugs which need to be worked out. The devs have a few ways to reduce this. More rigourous scrutiny of the codes (not foolproof) which will mean even more delay for new things to be introduced or testing. Pay to test is not of course profitable or in the company's interest. However open testing may kill the impact of an event or anything which is supposed to be new.
At the moment, we have too few people in PTS who are actually testing out the new releases and it is impossible to simulate anything close to when the new introduction goes live. Hence bugs do slip through. The Live shard becomes almost like the test shard. If things do not go well, take it off and try to fix it. This is bad because the damage done may be irreversable. Even a rollback (assuming there is a backup) will still have impacts on players who have gain anything during the rollout.
As such, I strongly urge gold players to be more active in helping to test in PTS and also the devs to occasionally open the PTS for silver players when you need larger numbers to help in the testing.
