the aggresive icon when it comes to mob groups

[Jinko]

Point being:
Its nice to know the level and aggresive status of a mob, but its pointless to have to stare at it all the time.
You only see a mob's HP bar when targetting it, there's a reason you don't see them floating above every mob's name. Its information that when not being used is useless but that within the right context (in that case, of battle) isn't.

FWIW most MMO's have the option to toggle HP bars on and off above the monsters heads.

LOL @ "how the pro and true adventurer plays", if you think punching yourself in the balls just for the hell of it is pro then sure, have a cookie.
