I partially agree on this one but having moons in HS also came with a secondary upside for corporations which was the ability to determine when the mining field spawns. So it allowed also people that are not going to log in right after downtime to join the mining fleets. We did find a great increase in mining together compared to every man split into different systems trying to find a belt that is not mined out.
I would had been more than happy to even have just the low end ores that you can find in the asteroid belts but now that they are gone the game is again heavily favoring people who are able to log in after downtime to mine the belts first and the moons with low value stuff are now left to other zones.
