Currently when killing any mob all you really see if them fade out, i cant help but feel it could be more dramatic.

Instead of normal monsters just fading out they could instead turn into pyreflies like in FFX or something similar, just to jazz it up a little.

Big Bosses such as those found at the end of dungeons could take it a step further and scripted death scenes after being defeated, be it in a cutscene or just in /say once it dies... It'd be fun to see the enemy cry out that they're gonna come back and get you at some point or something of the like.
