To get more agro, you need more swings and more procs, and higher agro per proc. Hitting harder or procing for more will not increase agro. In fact, you can keep agro while doing zero damage (for instance, while fighting Emperor Ssraeshza). So, combat fury and ingenuity do nothing for agro. The first agro AA you should buy is ambidexterity- it increases dual wield by about 9%, which means something like a 6% increase in both dps and agro, for only 9 points. And it doesn't get upgraded, so once you buy it, you're DONE. Savor that rarest of feelings in EQ...hehe.
Another important thing to keep in mind is that many of the basic AAs give the most bang for the buck at the beginning, in the first few ranks. Be sure to at least max out the Luclin defensive and hit point AAs, as they make a huge difference for very few points. Planar power, too. And area taunt often means the difference between life and death for a squishy. Gotta be close to use it.
In terms of procs, you want something with a detrimental effect in it like stun, snare, slow, etc. That part of the proc usually adds 400 agro. A DD adds one agro per point of base damage. For instance, Chaotic Strike V has a 200dd and a stun, so it's 600 total agro. IIRC, weapon affinity 5 increases procs by 50%, so that's definitely a line you want to max out. As you continue to level up, agro will become more important and harder to get, so it's good to get in good spending habits now. Don't wait until you get asked to a difficult zone to find out that you can't keep agro off the 85 rogue. This will hurt your rep, especially if they look at your gear and notice you're using a weapon without an agro proc.
