Here is my opinion:
There was an issue with that shard when it was created. For whatever reason (some seem to think it came from the most active players hitting “join” the moment the fleet function went active), this one shard had way more competitive players in it than most.
After awhile, CG acted to address this but splitting the shard in 2. This presumably cut the number of “super active” players in half for each of the 2 sub-shards.
That still leaves 2 shards with a lot of active players. Probably they are 2 of the most active fleet shards on the game. Maybe even the top 2, who knows.
But at the end of the day, one shard has to be the most active. There is not much point of trying to prove that your shard is the “most” active, or that it’s top 2, top 5, etc. If they took action to address the “most active” shard that would only serve to make the second most active shard step up to take its place. Someone always has to be at the top.
The real question is:
Is this shard so much of an anomaly compared to other shards that more action needs to be taken?
Based on the silence from developers on the topic, it seems that they don’t. They put a fix in place and the two resultant shards are “close enough” to others (in their opinion) that no further action is warranted.
There is really no way for us to compare that ourselves as we simply don’t have the amount of data available to us that they do.
I feel your pain, as I’m in a fleet shard that I believe is “more active than average” but it’s just the way it is. By definition, about half of the shards will be “busier than average”.
TLDR - Don’t hold your breath waiting for this to be addressed any further.
