What exactly is changing with Chaos?

You guys also forgot about the revamped scrolls. Defense, HP, MP, accuracy and avoidability scrolls will be strengthened to give 5 times more of their respective stats.

One big question: I've got reports from friends playing Tespia that LHC's spawn will get dramatically reduced with chaos. They said it might turn LHC into a not good training area driving people out of it to train in regular maps. IS THIS TRUE? (yah I know gate tu the future is coming out but ignore that for this response).

LHC's spawn increases based on how many people are in your map
i doubt that a tespia LHC map had too many people in it, which is why your friends might say this
