In a recent tweet the Warcraft devs have promised to bring some much needed relief to the queues on many of the high population servers both in North America and in Europe.
Some servers are seeing hour long queues over half a year after the initial release of classic, which certainly is impressive for a 15 year old game and brings some promise to the longevity of Classic WoW.
We've been working on bringing some relief from the queues to the highest-population WoW Classic realms in both the Americas and EU. We'll roll that out in the coming days, after we test it internally. Thank you for your patience. https://t.co/lTwIfXwfeV
