We can use the mineral deposits into closed gate as a proxy for player activeness pre and post patch.
This isnt the most accurate way, but probably the best way to estimate it for now.
The mineral deposit aspect has not really been affected since the latest patch.
Give it a few days lag, due to we can deposit materials way before the gate opens, and that some players had left over minerals from last week.
The current gate has around 50k for each type in stratum 1, and if one week later the gate about to open has the same amount, then player activity remained the same pre and post patch.
If its significantly lower, keep doing what u're doing, and 3 Ring's will be forced to undo the changes or at least do something else to make their players happy, or else they'll only keep on losing profits over the most critical part of the game's life cycle.
If the numbers are significantly higher, some gm's must be adjusting the results.
Also I expect this topic to be closed, but guess what i dun really give a flying f*** bout this game anymore.
When facing a significant loss of customers after one change (purely my assumptions based on forums / friend list / guild / in game chat ), if you don't plan on doing anything to restore it, you might as well ignore any bug fix. I think the most important thing you should do is prepare a fancier report to your board members / corporate investors. Since u're not getting as much from ur customers, you should at least try to get that from ur investors.
