Guild Wars 2

is it worth my time to work on the fine infusions with both a stat and agony resistance or would i be better off with just the simple agony infusion? does any of the stats make a difference?

You can buy the wvw one with laurels and badges. You also get some extra dmg/defense against guards.

If you already have the rings there is not a good reason to keep doing fractals anyway. IMO it is a waste of gold to get the angony infusions when the wvw ones are cheaper and better.

I would also avoid making the 5 stat/5 AR ones until after HoT releases in case they add new things for it.
