Honestly I didn't think about how long will Justin stay, so I totally get your point saying we must take benefit of his presence to make these changes fast.
But to me this passing subject, as other subjects, could be dealt with a salary formula update first. It makes no sense that centers can get 20+ Pa with no impact on their salary while guards hardly can get more than 14 Pa. And there should be a preliminary notice so that we can adapt cause, yes, training players and building teams take time. A lot of time. And the slightest changes can get your team from a title contender to not much anymore.
This game is slow, yes, but as many other strategic games. It doesn't mean it is out of date but I understand you try to find ways to get and retain more players. I thought the app would help, as well as Justin's huge work, but maybe it just helped reducing the user loss so far ?
