In the real world companies test things before they roll them out. How hard would it have been to take a strong, medium, and weak player in each of the tiers and tested the result of this boss event on each players stats? You could have easily seen how much gold was necessary to reach each level, or lack of gold, and plan accordingly. This single event, you have rolled out, has alienated a good portion of your player base. Sadly, i join the crowd now of not buying gold anymore as my player is now obselete with very little opportunity to make up the 500k in stats that i wasn't afforded, a somewhat reasonable, opportunity to gain.
