The issue with Null is the base, which is present on every version of the map. It is huge, and is likely what is causing strain on many peoples PCs and is what causes crashes. It needs split into seperate peices, like the ISD is on Hoth, to elminate the issue.
Null16p is, however, less likely to crash the server than the other versions of Null (players may still CTD), as it's belived that the server instability during null is caused by the APC Freerunners, which pretty awful collision meshes and make the server take a fit when it tries to climb up a really narrow hill.
I'd love to see null fixed, it's definately one of the best 16 player maps, and I also really like the valley fighting in the other versions.
