In addition, I recall pvp videos of classic wow gold a hunting down 60 warriors. Not just that but in one of Vurtne's pvp movie's he is on his shaman alt combating 60 completely geared mages and constantly getting the interrupts. Enough to earn a part of his movie saying"look how simple shaman vs mage is" that simply doesn't seem likely on private servers. Hopefully somebody else recalls this.It will be interesting to see at what stage people draw the line for making modifications (if any) to classic servers. Sure, everything is the way WoW Classic was intended to be played back in the afternoon and needs to be kept that way. However, some things for instance, such as the availability/support for large public servers (much higher than back in the day) and therefore changes to world respawns seems like it might be an issue down the road, particularly with the limited number of accessible servers at launch.
Any idea about leveling time out of 1-60? Back then a lot of what made leveling to 60 was the fact that you had no idea what you we doing. You had to team up for certain quests. Studying the quest log and so on. Personally I consider the journey to 60 the most fascinating portion of WoW Classic, as I was not a hardcore gamer capable to put in 6 hours every day. I hope to eventually raid, and respect that some people may play more than others, but I fear of being defeated before I login.
My guess is that you are wrong about armor/resistance reduction. There were plenty of examples in vanilla of similar abilities stacking, and sometimes people exploited that. It's possible that the foundation way armor and resistance function is incorrect on private servers, which might also account for a lot of differences. But my guess is that every armor reducing capability will stack with one another. Generally in elysium project gold, similar consequences piled, but the exact same skill didn't (that is the reason why just 1 battle yell could be active, and why you can not just spam warriors to all sunder armor and garbage the boss).
