Wyrsza, this isn't a flame, and I understand what you're saying. However, the simple truth about the technical issues you mentioned is that everyone on the Virtrium team is well aware of them. "Make it work with Vista" isn't a suggestion; it's an operational milestone.
I'll accept that you have the knowledge of MMOs that you've asserted you do; based on that background, it should be obvious that the overhaul you are talking about is already in progress, in sections and stages, and will be an ongoing 'to-do' list for the technical team.
On the other hand, good suggestions on gameplay, NPCs, quests, lore, etc. may be things which will significantly improve the game and which can be implemented with the team's current resources. That's also part of the game reaching its full potential. By all means, if you have such ideas, develop and present them. Even if they can't be implemented for some reason, they may spark an idea that can.
