Sorry, what I meant for B ranks was based off the original spawn timers.

The whole idea is to make them for the most part untrackable as they will get killed so quickly and so often. For an example, I can look at a spreadsheet for my server and tell you that Melt (A rank) must spawn in the next 10 minute, then it is 5 minutes from now that the chance for Dalvag's Final Flame to spawn begins. I personally don't find this enjoyable as there are over a hundred players in one large group just searching these particular zones since they are tracked with such ease.
