Talk:Enemy Level Scaling/@comment-108.74.29.47-20150227165811/@comment-20753550-20150401114301

This article covers how enemy stats change with their level. It does not cover how enemy levels change with the mission time in endless mission types. So unfortunately, it doesn't contain what you were looking for.

In fact, as of my knowledge, no study on the occurence of enemy levels at certain times / states of progress in endless missions has been published yet - which is quite surprising when you think about how important this is.

Perhaps we see a community collaboration on this subject in the future, so information about this may be added to the respective mission types' articles.
