No, it's hard- Which is part of the reason why they should be open to suggestions from the people who have spent so much time playing and understanding their game. We have Excel spreadsheets that will predict exactly how much damage a spell or weapon skill will do at any given time, I think we deserve a little more respect when it comes to suggestions on game mechanics and balance.
Also, just because it's hard doesn't mean they shouldn't be able to do it (to an acceptable degree, at the very least). There's a difference between attempting, failing, then genuinely attempting to correct your mistakes and just stubbornly repeating the same mistakes over and over again for years. They have always been, and probably always will be, simply (simply has more than one meaning here) of the opinion that it's better for them to try and fail for 10 years than to be "open-minded" enough to listen to their players at all.
When this forum opened is when FFXI began to peak (in the context of the game, not popularity). It didn't take long at all to start moving downhill. They read suggestions, they thought about them, and they appeared to even consider them at first. Now, I doubt they do more than glance at the NA players' suggestions just to see if they can give us a translated response to something from the JP side- which they listen to but still don't honestly consider.
If you go back and read the "responses" to the opinions and suggestions we had after they originally shared the Job Manifesto you'll see this. We have RDMs discussing the significance of Cure-tiers and brainstorming directions for their job and then we get a reply from SE that quotes and answers Japanese players saying that they want to be able to melee and unlock more weapon skills. This sort of thing is just unacceptable. I'm not asking for NA players to get more attention than JP players because we make up such a larger portion of the playerbase, but I think that at least deserves us acknowledgement of some kind. It's like they don't even consider us to be the actual players of the game, even though we're the large majority.
It is hard, and I'd defend them too if we were in this together- but we're not. We've been trying for 10 years to share our experiences with the game and our ideas for positive directions with them, we complained about DRG for 5-6 years and laid out specific problems and different paths to fix them before they even touched it. After throwing comments and suggestions into their e-mail trash can for eight years, we thought they were changing- but it feels like they backed out at the last second.
