The herald system sucks, regardless of spawn rate or not. The 30 minute TZ timer is also junk.
The only good thing this "expansion" added was stack-able items, hardly worth putting up with the game becoming a tedious dumpster fire.
I’m sliding right into agreement with this. If it wasn’t for the convenience of stacking gems and runes I’d go right back to how it was. In fact I left a few characters unconverted and I’m thankful for that right now.
