I can agree with that to an extent, although easy servers that managed to get a lot of hype before releasing have always thrived, even way back when. Economy servers have always had their place too, but as I mentioned somewhere recently, about half the top servers are PK/spawn servers and that isn't entirely something "new" that has become popular only recently.
Anyway we can't be a successful economy server if we do resets, it kind of goes against the point. A spawn server can easily be reset because at the end of the day it's a spawn server and there are no major losses; resetting an economy based server actually screws long term players over in a way that they don't just recover from in a few days. Especially when you consider the point that you want a reset is because there are too many items or whatever you think is bad, to avoid a repeat would mean making it harder which just hurts long standing players even further.
A more ideal solution is the proposed balanced of the hard mode/group ironman, where everything would be harder and the economy of those accounts would be limited to others in that mode, allowing the normal mode to stay the same or even become easier to further separate the two. This way the people who WANT to game to be challenging and items costing money out the ass can have that, while others who are looking for a more casual play compared to OSRS still have that and without resetting anyone.
