The problems with running custom map packs (in my eyes) are logistics, verification, and interpretation of glitches.
Every server would need to have these maps in their rotation, and some server owners are more willing to install the maps than others. Some server owners are also much more easily contacted than others. Those server owners that are particularly difficult to reach might be running the best suited server for two teams. This creates another cause for conflict between teams.
It could also be difficult to tell which version of the map you're on. You would need to deliberately test specific areas on each map to determine if it was lust's "fixed" version or the native version. I can easily see disputes being raised about whether or not the correct version of a map was used, and I can also imagine the ill will I'd quickly get from the community by saying "screenshots or gtfo."
Then there's the interpretation of what actually is and isn't broken. Lust already brought up one of the biggest issues here: the linens hanging around Village. I'm of the opinion that the linens over the cushions at the wall (near the portcullis tower) are legitimate spots, while the other linens around the map are exceptionally difficult to reach and thus more likely glitches. The broken walls around Ruins are another thing I consider not to be glitches, just tricky jumps, and they don't really convey much of an advantage considering there is no cover from ranged troops on top of them. For Nord Town, it's my opinion that the carts need to both be blocked off or both remain open, as they both provide entrance to areas that otherwise have only one entrance. Removing access to one makes that spawn area arbitrarily more advantageous.
