First of all, Kudos to the staff for actually trying to address a problem and (hopefully) being willing to discuss it.
I'd also like to remind some people who have been screaming bloody murder about this that you were already complaining about the status quo, before this was posted, and that most of you have not yet offered any concrete solution.
Personally I'd like to raise a few concerns, suggestions, and questions:
1. I think that credit fines and activity requirements make sense for requests that benefit or "satisfy" only the players making the request (for example someone asking for a monument for one of their heroic chars in an infocard). However, there are probably also those kinds of request that can make the mod unambiguously "better" for players in general (for example something that enhances gameplay by creating and activity hot spot or telling an immersive story). This should probably be free of credit or activity requirements.
2. How will the devs themselves handle their own storyline progressions and faction developments, which are bound to benefit some factions/players and not others? How will you guarantee that you wont slip certain "requests" made behind closed doors in the mod free of credits but not free of personal bias (assuming you keep the mentioned requirements).
3. I strongly encourage you to add a layer of community quality control to requests to find out about possible plot holes, contradictions, and possibly woes the community will have with something BEFORE you implement them (you will inevitably hear about it afterwards anyway). This could be done by making requests visible, and giving the community the opportunity to give feedback (which staff or the person requesting have no obligation to take into account), leaving the requesting person the opportunity to correct mistakes or include good ideas that they didn't have.
4. There appears to be a feeling of "entitlement" among parts of the community that their RP has to be taken into account, which is often a bit problematic. I fear that adding a fee and activity requirements will only add to that feeling of entitlement once those 2 criteria were fulfilled, and will only increase anger when things are rejected.
