I was dusting off some things and took a look at my guardian’s Givers set and I must say overall its disappointing.
My suggestion to make this set a bit more useful would be to increase the Boon duration that is on each piece. As it is right now if you compare most gear (Magic Find included) most pieces have a min of 3% while all givers has 1% on gear and 2% on accessories
My suggestion is not to change the stat completely just increase the percentage to the gear.
At the moment the boon duration totals about 15% an increase to 3% on gear and 6% on accessories would bump it to about 48% making it much more appealing to those who wish to play a more support role for groups.
