Another Agility Thread

[Knuckle]

Was chatting with a guildie about loot and they said Ikky legs better than Dagarn legs for monk due to the agility. I had just acquired dagarn legs and I honestly had never heard AGI having any significant impact on p99 for any class. does anyone know the direct impact of agility, and what would say capping 255 agi vs 100 agi actually do for a level 60 monk when tanking a mob? I feel good about the Wurm Legs and don't plan on changing but curious if I have undervalued AGI in general.
