Sometimes it is hard to tell how many monsters are alive around you, especially when there are many visual effects on screen. Is it possible to make this more clear, like adding red outlines to damaged creatures or maybe health bars (Diablo 3 does this)? See examples screenshots below.
In first screen it is not really clear how many monsters are on the left side, in second screen there is obviously 1 being attacked, then there are 2 behind him if you look closely and then there is unclear how many are alive behind these 3.
