Possible aggro control - or maybe even a new skill mechanic

b00tik

Speaking in layman's terms - about about a aggro over time skill - something that you can stack single target or even spec into that allows tanks to gather an AOE type aggro? a skill that is a minor bleed and stacks Area of Effect for an aggro skill? after speding a heavy amount of points into a certain area kind of skill that allows you to stack Area Of Effect threat through a damage over time spell onto many monsters? would this not solve the current healer threat problem? Mind you to an extent after fixing the current ratios of threat gain?
