You say GBX doesn’t care but they have made changes attempting to accomodate everyone they can.
Players were unable to find games on certain platforms, so they loosened the ELO ranges so players could find games quicker.
This caused experienced players to be matched with less experienced players, lessening both parties enjoyment, so they changed the queues into into Competitive and Casual, with all gametypes in both queues to consolidate the already low player base.
The Competitive queue is for players looking to play with similarly skilled players that don’t mind waiting for such a match, and the Casual queue is so players can find games as quickly as possible if they are indifferent to the skill level of other players in their game.
Now people are upset with the results that GBX said would occur. They stated the Competitive queue would have longer wait times, and that Causual has no ELO requirements for forming matches, but people complain as if they were unintended consequences.
They have to pick one or the other. Longer wait times, or the possibility of playing with players above or below their skill level.
All the old and new problems are stemming from the main issue that the game lacks a large, diverse player base.
There is nothing GBX can do to solve this short of making the game free to play in hopes more will give it a go, but even that will cause players to be upset that they had to pay full price for the game that became free months later.
No matter what they do, someone is going to be unhappy, but to say they aren’t listening and don’t care just because they can’t solve an issue they truly have no control over is ignorant.
They have made multiple attempts to improve things for the better, and plan to make more changes in an attempt to further improve the situation. That’s all they can do.
