Initially, I believe you can recover the exact letter on the lodestone if you look, but the 1.0 world used a ton of repeating textures was very large with little in the area of special. it had huge zones which ate up tons of server utilization due to supporting zones that were inactive. the new layout was an attempt to create a fresh unique set of zones. and due to this smaller size, which is mentioned in the letter. that also goes on to describe 1.0s fundamentally flawed design and intentions to use zones to conserve resources. they also went on to mention that design elements of the old game made things like equipping and UI aspects laggy due to programming methods and data calls to the server. it would be very much a mistake to think that past memories of a grandiose 1.0, though graphically better, nearly every aspect has been immensely improved in 2.0. which has only been out since august. Kinda long and not broken I suggest you find the letter its much better.
