green vs rare or exotic armor
it varies from mob to mob, but it generally is either how much dps you’re doing or how much toughness you have (or occasionally how close you are) will determine who aggros first
Geared in greens is one thing, using a maxed stat Exotic is another. I find that a balanced gear set will cause the agro to move towards the heavily damage or defense oriented players. As I use a balanced set, I tend to do fine even after the zerkers or defensively set up chars have been dispatched.
There’s also the mental aspect of it, if you’re in greens you’re more likely to keep your distance and play it safe. Whereas in Exotics you’ll probably feel a bit more confident and maybe stay in a bit longer, thus getting hit more.

Pretty sure it’s not toughness that matters, but your armor bonus.
