You did read his post, right? Let me paraphrase; "I earned my rank for a cutter in less than a week, it shouldn't be this way."
This is a game, not a job, not real life. Like FF11, the MMO, there's a reason only diehard FF fans played it. Some of the quest lines were over a year long and that's just not going to keep players around or entertained, especially when there is literally nothing else to do except put your nose to the grind stone to push up your rank or account balance. Nothing.
Well, let's start by recognising that you're conflating two separate discussions.
Firstly, there's the basic issue of whether it's reasonable to be able to achieve full military rank, and the ships that go with it, in a couple of days.
You can currently take on 20 missions which can all be completed with a single operation.
FDev are changing this so you'll only be able to complete 3 such missions at a time.
So, I think it's fair to say that FDev certainly DIDN'T intend for rank progression to be possible so quickly or they wouldn't have felt the need to change it.
Secondly, there's the issue with comparisons with real life.
I'll start by pointing out that it wasn't me who made that comparison.
Somebody else did that by saying "If I want to buy a car, I don't have to wait 20 years for it to arrive".
I dunno if that person is very rich and, as a result, is unfamiliar with the concept of saving-up but the simple fact is that most people certainly can't just go out and attain things as soon as they want them.
Whether or not that should be the case in a game is a different matter but, of course, the fact that FDev have sought to reduce people's ability to achieve things quickly suggests that's how
they want it.
Let's face it, if FDev
did want people to just be able to get Cutters and Corvettes in a short period, they could just bin the whole rank-progression thing entirely and set the game up to offer people a couple of Naval rank missions every day instead.
