You aren't kidding about Seru lol. Here is a pic that AndMetal sent me when he was testing hit new #aggrozone command:
I have seen some good train pics in my day, but nothing comes anywhere close to that lol.
Ya, a large portion of the pathing is not so great and some is just completely wrong. I imagine that people fighting in zones while packet collects were being done most likely threw off the pathing considerably. Since, a pull would probably be seen the same as normal pathing for the collects.
If it wasn't so much work, I would love to see the new path grid boxes setup in most outdoor zones. I think that would turn zones like GFay that take up hundreds or thousands of WPs and make them take almost none to have similar or better effects. But, there isn't an easy way to do that, as the only way to do it right would be manually and that would take forever.
