Just outraged that the signal was removed from the game by -10% to the cost of maintenance.
The claim that this replacement is beneficial for low-level ships is either made by stupid people, or by those who consider the players to be stupid.
Who in their right mind used this rare signal on low level ships?
I (and most players, I guess) have only used this signal on superships lately, and thus had a savings of 36k per battle.
Now instead of 3 signals that gave a guaranteed savings of 108 thousand, I get 1 bonus for + 20% credits. Very equal exchange, aha!
Say straight out that you removed this signal because it was very good on superships, and you just decided to "tighten the screws" and did not at all strive to make the system simpler.
