WoW-Reign is a Cataclysm Private Server, that says that they're a "blizzlike server", which tries to give an authentic experience. They however note that they have added a few adjustments to make the game more active. WoW-Reign was released as a Cata Server back in 2019, but is however quite low in population. The population of WoW-Reign is between 50-150 players, usually. They have an active bugtracker, meaning they do have an active development team, who are trying to improve their server. WoW-Reign claims that they are the Best Cataclysm Private Server. They are indeed quite stable, with low crashes and diff, we at Zremax do not believe it is the best scripted server. For the shop of WoWReign, they offer Vanity Items, Gold and VIP content. If you're into Cataclysm Servers with adjusted experience, and higher rates than 1X, and you don't mind a shop, and a less population, WoW-Reign might be a fit for you.
Solid server, there are bugs that still remain, but there is an active developer constantly working on the server and pushing fixes each week to make it better for the community. Fixes that come out are pretty accurate and basically spot-on for the most part when referencing a video from the actual expansion. The population is low but heroics, raids, and PvP still happen. PvP is usually scheduled among the two main guilds for Horde and Alliance to actually get something going due to the low pop.
I recommend this server to anyone looking for a blizzlike experience with Cataclysm.
In my opinion, the server needs a good rating, for at least trying. Their dev team is friendly and helping with bugs. The owner is trying to boost the server. It's however unfortunate that there aren't more people playing it, and I still believe they have a lot of bugs to fix :/
