I played classic a little bit and the response time from the game seems rather sluggish and slow?
I switched to retail and it’s not happening there. I do have relatively long loading times when I port to Dalaran that’s all.
I must admit I haven’t checked where the classic and retail EU servers are physically located.
Are they just cutting corners on classic servers, or is it just too much load at the moment?
They did this to try and simulate era-appropriate internet connection. Whose connection, though - although I started in 2008 I never had a ping above 50, however had some friends from South Africa…
Batching itself may have been a thing as well.
Its side effects are intentional, such as two mages successfully sheeping each other. Some other effects might not be so, many complain about hunter traps.
I got used to it after a few days. (I do manually loot, that was the worst.)
