Lost interest part way through the dev diary. Your players have been emphasising the ongoing issues, in game and optimization wise, for years. The team chose to ignore the core issues, and keep pushing forward with a broken game in favor of new content, only for it to bite them in the end. I have sympathy for the players who are dealing with this mess, especially at such a large scale with Titans and Meks. I truly do. However I'm really disappointed that new content outweighed the issues that keep stacking.
What I'm gathering from this is that they don't have enough testers for QA. I have no sympathy, that feels like an issue that should have been sorted out as the game grew. These new numbers with extinction, sure its impressive and I could understand if there wasn't such a backlog of issues and bugs that have been prevalent in the game for years now. The focus needs to shift and I really hope that it does, finally, after years of your players trying desperately to make these issues known to you.
