While I think it's nice they are making the game easier for new players I do find the icon extremely ugly.

Maybe I am a bit old school or am too nostalgic but I loved not knowing which enemy would come chasing after me in FFXI. Learning the mobs is an important part of any MMO to me and I feel like this icon not only takes away from the beauty of the game but also some of the sense of danger, which if I'm not mistaken, the dev. team is trying to create that danger.

At the very least have an option to toggle the aggro icon.
