Thx for the insult.
Anyhow, you're compairing apples to oranges. It's quite oblius in a book fiction you can't see a dialog like "hold on, let me check if that dude is hostyle on my hud", since it need to be a plausible environement.
the same can't be for videogames, since you need to think how blend together a plausible environement WITH friendly commands, balance battle content, offering always better fights and quests.
Now, since FF XI, mmorpgs are more evoluted, and whatever you like it or no, aggro indicators near the name is a standard the facto. Deal with it.
And remember, if you're aiming to the wides audience you can have, a stupid icon is the lowest of your priorities. If SE would do another elitist mmorpg, then they could just redo ffxi with next gen graphic without abyssea, or else an hard-kicking game like could be demon's soul. but then don't expect huge profits
