The reason why servers like Grobbulus and fresh servers have this gigantic queue is because they remain relatively balanced faction-wise.
This issue is affecting two types of servers present in Classic WoW.
I jumped into WoW Classic (in the morning during work, a luxury many don’t have) to find out how people are getting in.
The first are the long-standing servers that have maintained a large population since Classic first launched back in 2019, like Grobbulus in the EU region.
