Not only smaller, but far more intuitive. It does me no good when I'm trying to tab around to an enemy right in front of me, and it targets some random mob way off in the distance to the left practically off my screen. Precise tabbing to other targets in front of you is next to impossible when you have a large number of mobs on screen (FATEs, dungeons, etc.), which has proven incredibly aggravating on many occasions. Tab targeting needs a good overhaul.
