The real difficulties that have arisen here have seemed to be like a slow-motion train-wreck from the start.
1: FCs announced, with some nebulous talk about them being "expensive" and "only affordable by a very few"
2: Borann mining rush started, with the discovery that mining LTDs wasn't throttled in the same way as VOs were
It's at that point, that
someone at Frontier should have either said
"This is fine, we really intended everyone to have an FC anyway, let them mine"
or
"Hold on a moment... this is going to ruin the game mechanic and intention of allowing only a few carriers to be available"
But they didn't. So the mining continued, and some people accumulated multi-billions worth of credits.
3: The FC announcement of the cost of the carriers and the upkeep came out. Mining intensified.
Again, this could have been an opportunity to think carefully about what was going on, and what the outcomes would be, but it didn't happen.
4: Upkeep costs reduced, patch finally delivered after 2 betas. Mining continues, credits accumulate for those people continuing to mine
5: Carrier explosion. Tritium trading added to LTD mining profit options. More credits for people taking advantage.
6: Eventual throttling and attempts to control mining and tritium credits with FC-patch 3.
Net end results:
a: Fleet Carrier infestation causing performance issues, and poor sysmap representations.
b: Major imbalance between credits of those who mined, and those who did not, leading to:
i) One tranche of players with an FC and billions in the bank, in some cases enough for 11 years worth of FC upkeep.
ii) Another tranche of players who are probably where the original intention of Carriers was, which is several billion away from owning an FC if they want one, and probably now put off trying to get one at all, due to the time involved that is necessary.
Frontier are in a bit of a cleft stick at this point:
For the people that didn't take up mining, with the reasonable expectation that Frontier's silence on the matter was an implicit approval of the mining economy, the sudden removal is going to look like an unfair move that punishes them whilst "rewarding" the players who did take advantage. And I can't see how that looks good, from any angle.
If they didn't take some action to stop the mining / tritium profits though, the carrier infestation was going to get worse, especially at mining sites, and the performance problems would degrade further.
If they try to redress the balance by taking away assets and credits from the players that did take advantage though, that is going to be "somewhat unpopular", and in Sir Humphrey Appleby terms, "a courageous move"
Any which way, it looks like they don't know what they are intending for the game to be, and reactively panic managed the whole release.
