While most players may not feel the need to be told what aggro's it still helps with more inexperienced players who get frustated easily and especially in party situations.

From past experiences in FFXI you'll sometimes run across a player or two that holds up the party because they got aggro from something they had no knowledge about. They die, homepoint, and have to run back or you have to send out a raise for them. Even in Abyssea parties this type of stuff happens where some people have no clue and either die, ask about the potential aggro, or you have to go guide them safely to camp.

Oh yeah and on the subject of a "link" icon. Who remembers good old low level parties and your recently invited puller linking everything cause he/she didn't know they did? Then the party disbands after the 2nd wipe... (Talking about the poor ones. Not having a go at the good pullers out there who know what they are doing).

The issue then splits 2 ways:

With newer players who get aggro and die, they can possibly become annoyed and log. This can result in the end of a party if there's noone available to rep. The player may even possibly quit the game which while veteran players may scoff at and say they are better off playing WoW: it's still a lost subscription to SE = bad.

And with the more experienced players, they too can cause the end of a party as a good number won't put up with some newbie getting themselves and/or the party killed. They'll just find it a waste of their time and leave.

Anyway if you feel you don't need the aggro icon and you can learn what aggro's by yourself thats fine. If that's the case then the aggro icon was clearly not meant for you and the planned toggle feature will be handy. As for other players than just yourself: it's up to them if they feel they need it or not.

Toggle option does sound fine though it'd still be nice to also have the info display only when a mob is targetted. Another option I like which I have seen is having the info display only when you get close enough to a mob.

Two other things I'd like to see is having agressive mobs show as another colour on the minimap like the classic red dot. And secondly it would be nice to have a better visual method of showing that you have aggro'd a mob. Usually the first sign you get is suddenly falling to the ground with "mob hits you for xxxx damage" in the chatlog.

Having a better warning that a mob has been aggro'd would help reaction time to either run away or prepare to fight. Rather than there stand clueless and get pummeled. It may ruin the immersion for some players though so maybe have it built into the toggleable aggro icon so it has an idle and active state. Like have the aggro icon yellow as "caution" and turn red if you aggro.
