I think the gold should be increased again. All the way back to 300/critter? I'm not sure. My guild has the great good fortune of having a number of EOC players - and maintaining guild gold balance since we crossed the 1600/1626 thresholds has been harder. Some habits have had to change (I no longer Hellforge high level guild gear each hunt as I did pre 1600), and the odd gold drive has been had.
Using cost of quest items from shops as a reason for more gold/critter is a fairly weak argument in my opinion, and is perhaps borne of the agony that is Crestoun and the constant need in those levels to buy quest items etc., but post 1600 it has not been crippling (again, in my opinion).
The gold/FSP exchange is stable well south of 200k/dot most of the time, which is good for the overall health of the game I think - is this because the high end players are no longer coining it every hunt? I used to hellforge because I had gold to spare. Now I don't, and have to make choices about how best to deploy resources. I certainly was not worrying about that at 300 gold/critter.
So I think maybe with a new release of content increase the gold to 250/critter. And watch the FSP marketplace to see how it reacts. I for one do not want to strangle the FSP supply to players with more limited resources for the sake of more gold/hunt for me, even if that would make my life as guild founder easier.
My possibly misguided 2d (old money!)
And BG - don't let this delay that content you promised todayish!! LOL!
