Thats not true in many ways.
T15 Bis and T16 Bis have nearly the same critrating! So at beginnig of T16 critrating is going to drop a little bit, what makes the new 4pc just more stronger.With 574 Heroic pieces (2/2 non-warforged) our crit levels are going to be incredibly high already.
No. For Every ATcomb u have 2 garanteed Pyrocrits out of 4 Pyros. For every nonATcomb u have at least 1Pyrocrit. At actual gear it can happen, that you have 2 noncrits for your nonATcomb even at high critlevels. This is never going to happen again with the new 4pc.the set bonuses are both underwhelming
No again. Every Setpiece has crit on it. To make up 4pc e.g. for ATcombs u would need around 20%-30% more critrating to get the same results constantly which would be at least: (20/1,3)*600 = 9231 Critrating.I think the real discussion should be whether or not going for 4pc is optimal.
Since every setpiece already has crit u will NEVER EVER make this up.
Listen to what Hauntedd wrote. This is right.
