Does anyone from Pearl Abyss even respond to these suggestions?

A ton of content suggestions that come through here to increase/maintain player base/etc. is here.

Some suggestions don't even impact the cash flow for Pearl Abyss negatively and does not require a great deal in coding rework.

- What is the basis behind the decisions on what not to implement?

- Are there any financial analysis done on revenue impact on certain implementations if Pearl Abyss were to change the Guild versus Guild content?

- Are these game improvements not being implemented because there is no benefit to keeping up the game population? 

- Does PA only care to keep its current plan of action because 90% of its revenue comes from 200 players per server and why change because these players will continue their behavior purchasing patterns on maintaining the ever increasing power creep?

- Are there no true game improvements other than the release of pre-existing content from the Korean Version to Global? Who is coming up with what classes to rework and balance?

- Are there no game improvements because Pearl Abyss has already received a generous return on investment in this game that any new content will result in diminishing returns?

I just would like to understand why it always seems like great suggestions continue to fall on deaf ears and blind eyes.
