Those Merit farming the closest systems. ALD was by far the worst for it.
No efforts made to contest (undermine) ALD's systems.
Big efforts where made by them to expand only.
ALD was not the worst for farming the closest system. We were the best at preventing it. Having said that, merit farmers were not the cause of the problem.
Your second point is fairly true. In the first week Aisling and ALD had a massive preparation war for one system. Aisling won, and after that the majority of players seemed unwilling for it to happen again. There was no more competition between ALD and Aisling for the next 4 weeks.
Only Panceinses was really contested after that, and this was by both federation and the alliance Power. The 3 of them together just don't have enough players. Perhaps they don't have enough combat focused (I don't mean they are bad at combat) players. ALDs expansion method is earning 1 merit per kill at a combat zone. Its a very poor return for your time compared to delivering cargo for the fortification and preparation missions.
Efforts were made to undermine ALD, but with the change to fortification, making it 5 times harder, this helped ALD and Aisling, because they have the player numbers to absorb the massive changes. Winters and Hudson had to dedicate more time to their now massively increased fortifications, which gives them less time to undermine.
I don't know what you are talking with the last point. There is no easy way to not expand. You only need 100 points for a system to be prepared. The minimum amount of preparation that ALD had for number 10 on their list was usually over 20000.
ALD started with more systems than Aisling, so this happened to her first. Aisling was running exactly 2 weeks behind. Aisling is just as unopposed, and would have hit the same wall in 5 days time.
As long as ALD and Aisling wont, or can't attack each other, there will be a massive imbalance in the game against them.
Mahon is flying at the same wall at an even faster pace.
Saving ALD may seem like favoritism (I don't think it was) but it will also save Aisling and Mahon from the same fate.
The guys at Torval did an excellent job (either accidentally or on purpose) of slowing their expansion and not being in Turmoil right now.
In week 2 ALD had a CC surplus of 1500.
After expanding to profitable systems, the CC went to 1400. Alarm bells should have been ringing at this point.
10 more profitable systems were expanded into, and the next week our CC was down to 1000.
Thats when I realized something was rotten in Denmark.
The forums had guys who had already figured out the overhead formula a week earlier. I used it and saw we would be in Turmoil the next week.
The only way to stop it was to not expand, all our systems were expanded, there is no mechanism to stop your own expansion, even though it was known it would hurt us.
So we went into Turmoil. And the game then allowed the next set of 8 systems to be expanded, while ALD was bankrupt and in Turmoil.
Not understanding the Overhead formula led to the problems, but the issue that caused the meltdown was allowing a bankrupted Power to expand and go further into negative CC.
The 7 (one didn't expand) systems all had a profit in game. They were all green, these 7 pushed the overhead cost so high not one system could be afforded anymore.
If there are changes made to the game, the costs need to be actually shown in the game. You can't have this system where there is no form of communication between the players, and every player is expected to understand that when they see a systems has a profit of 100cc, they have to actually calculate the overhead expense and take that away from what the game calls "profit", to see the actual profit.
Thats the simpler answer to what happened. What the game calls profit isn't. What it calls profit is income minus upkeep costs. But there is also an overhead cost, the game should subtract both costs from the income and call that number the profit.
