Easier build crafting? But this allows you to have complete sets, if you put the effort in. Activating Armor Boost, Keen Edge, Shield Wall and Smashing Hammer.
You either use another Legendary, without a set bonus, or this, which grands a greater set bonus AND activates the 4 above buffs. Where's the downside? It's not as easy to build sets?
We have been asked for more sets that have greater numbers of items and now, the more items in a set, the greater the set bonus. It's no longer just one more items worth of stats.
