Just disable God items in WoE if you're making across the board changes.
I think it's a bit late for any true impact. Nothing was done when God items were being siphoned from other people's hard work.
Multiple sets being able to be made in a seal roll was your [The GMs] fault and is what lead to this.
No one can fault Xellie, she earned what she has. You can't just change the rules now though.
God items do have a bigger impact on Classic, true, but that alone isn't what will deter people from joining, nor do I consider it a major reason.
The server needs to be fun. It's stuck in a monotony that's WoE. It needs to at least be appealing outside of WoE, even if the veterans won't participate.
I can admit things are appealing even if I choose not to participate.
At this point it's a battle of pride. Tolrin and Xellie are both just too invested and they have friends that are loyal to them.
I can almost assure you that hardly any of them log in for more than 6 hours a week.
