Everything is to be taken in context, really. People who are looking at a high-rate server, and see drop rates higher than say, 100x, should expect that (unless the drop tables are customized/altered in some way) that things will be easier to come by via farming, and won't hold much ground in the marketplace. It comes with the territory of being a high-rate server.
If you have a high-rate server with a fantastic quality, it will most likely be reflected in player reviews, or hell, even your advertising. Jesus became famous by performing similar miracles.
(But in all seriousness, yeah.)
And whats this about stability? Do you mean uptime vs. downtime? In my humblest of opinions, if a server is crashing because the high rates are 'too much' for the hardware to handle, the owner either needs to upgrade or lower the rates. High rates are not an excuse for not delivering the most basic of needs. If i read the 'stability' part wrong, my apologies.
