Nah, I am still for removing that route altogether. All the Wild near the New Berlin jump hole aren't helping since all the traders easily avoid them as they jump out of the TL 4k before the jump hole, meanwhile the insane numbers and armour of the Wild keeps pirates away from them. So the NPCs are actually helping the traders funnily enough.
There can be plenty new routes that are just as profitable as the diamond run, but I still opt for that one to be removed. As long as it exists OORP power traders will use it. Make a diamond route to Liberty and Bretonia instead, at least you can make it less OORP that way by the fact that they don't go through Chugoku but the way it should be through Omega's/Hudson.
OPG would have more stuff to do in the Omegas then as well:P
