First, let me say I like the new NMs. It's great that my friends and I can go smack down a NM when we feel like it. The drop rates might not be the greatest but the pop times are short enough that it really doesn't matter.
However, there is no thrill in finding these monsters. They are up, or are usually up unless they have just been killed. One thing that always made my heart jump in FFXI was when I would be killing placeholders, and then the NM pops. Even when it's low level NMs like Jaggedy-Eared Jack, my adrenaline would start pumping between seeing it and actually claiming it.
I'm not asking for ridiculous pop times or epic loot, I just want NMs that spawn in place of the same mob type on occasion.
To summarize, I would like to see NMs that provide "the thrill of the hunt" by spawning from the same mob type.
