I prefer the following XML snippets
Code:
<ImageStyle Name="exp22_dun_plane_of_avarice_02" displayname="Gerion: Dominion of Pain" zonerect="-540, -35, -147, 423">
<ImageFrame Source="images/maps/exp22_dun_plane_of_avarice_02.dds" SourceRect="0,0,436,508" />
</ImageStyle>
This reduces the Solo, Heroic, and Untold dungeons into a single map that shares POIs. The three dungeons are basically the same map and POIs already.
