What? A game designer is OK to be to lazy or cheap to purchase a thesaurus and dictionary?
Shall we discus bloodied, or an even hotter topic of the misnomer variety the "hit points" and "damage", or have they been discussed enough for you?
The first step taken to simplify the system to streamline it should have not be redesigning a language to fit some keyword system, but finding the correct words to use in the first place.
What is a controller? One who controls. Does controlling always dictate killing? Can one person on the combat field "control" the battle? If they can, then what are all the other people of the party needed for?
Likewise defining "role" as combat position rather than what the term was intended at the games inception as the simple thing of making the decisions for a fictional entity. You assume the role of that entity within the game.
I could list mountains of bad choices from 4th edition alone in terms of terms used that were bad choices where another word could have been used better to prevent flawed design via flawed concepts and ideas due to using the wrong words to describe them.
No wonder the published adventures don't have much in the way of descriptive elements outside of combat because the descriptions are lost to current designers who cannot figure out how to use the language.
DM: You stumble across a bloodied corpse.
PC#1: So it is dead or just below half hit points?
PC#2: Look out! Its an undead and may recharge its encounter power soon!
Sheesh!
What will people think when they read someone is bloodied in a Greenwood or Salvatore novel in the future?
"Drizzt lifted himself from the crevasse bloodied from the fall."
So was he just covered in minor scrapes and scratches that caused him to be covered in blood, or did he take damage equal to or more than half his hit points?
....
@Siberys:
I do think they could have chosen many terms more carefully, as proven by the whole lead up to 4th edition by always saying its "cool", and people around here stuck on the term "awesome".
One of the things lost from Gygax prose...the prose.
