I think you misunderstand. When suggesting, people are not saying "IMPLEMENT THIS NOW BEFORE YOU DEVELOP ANYTHING ELSE!" (at least most people aren't)
They are to give ideas on how to improve the game once they get things going or perhaps to aid them in directing their "current development projects" as they continue working on the game. Suggestions are helpful either way. A good example is the marriage, relationship, and heir system that is currently under development (we assume, because our current content is bare-bones). People stating what they would like to see HELPS in development.
Bug fixes are always a work in progress, and balancing does not help much when a ton of new content still needs to be added. You want EA to be a polished product, but what I and possibly many others want is EA to be at least playable (not necessarily release-level polished) and for them to work on developing the bigger content (involving many of our suggestions) that the game currently lacks.
