As I've said before, the skepticism is much justified and for more reasons than the examples you've given.
1# What about monitoring Hard Lucid? 25 Star Enhancements and Flames? We haven't forgotten the claims that the content would be impossible for GMS without the addition of 25 Stars and Flames. Sure, it has been cleared already by a number of Maplers after Arcana and the increase to AF, but is it where we want it to be? Should hard Lucid only be cleared by the less than 1% population?
2# What about monitoring world population? Ever since the World Leap event, there were many concerns of low population worlds due to many Maplers moving to Bera. Is anything being done to address those who weren't able to leap due to bugs or issues in addition to the wider issue?
3# What about monitoring Kanna and other class balance? Ever since the changes to Haku's Blessing and even to Kishin, the class was reported by the community to be weak. Are there plans to address Kishin or make improvements to Kanna's current state?
4# What about monitoring the drop rate changes? Is anything being done to address the reports of low rates on acquiring symbols and droplets? What about Nebulites? Are there plans to make these more accessible? Not through events, but through pure in-game content.
5# What about the boss changes and KMS maps no longer being effective? What are these long term changes and will you truly make such changes to improve the meso income in Reboot?
6# Despite the justifiable skepticism, it's not a lie when we say that these issues aren't being forgotten.
Although this very message is the source of community frustrations, we're going to keep up our persistence to communicate these issues to you and the game teams.
