I was curious to see if anyone had done the math on this or had a link to a post on it (EJ forum maybe?).
Earthshatter-4 ~126Haste Rating
Worldbreaker-2 20% extra damage on SS and LL
126 is a lot of Haste to lose, but I still want to say that Worldbreaker 2pc wins.
However I'm not looking for any opinions here, just numbers.
