Did a quick search through the forums to see if anyone else feels the same way, but I didn’t find anything, so…
How about some monster family text under the health bar ala Diablo 2 for enemies? After making the carnal mistake of having the empowered Immortal Shaman trio suped up with over +80% damage and health granted to Undead Enemies Monolith buff, I realized that it couldn’t hurt to have that little bit of info after getting dumpstered in 2 seconds. If the desire is to keep the UI minimalistic then perhaps some sort of bestiary in the game guide down the pipe could fill the void.
